A comparison of physical properties for ionic and covalent compounds.
Views: 60232 IsaacsTEACH
To see all my Chemistry videos, check out http://socratic.org/chemistry How can you tell the difference between compounds that are ionic and molecular (also known as covalent)? It has to do with the elements that make them up: ionic compounds are made of metals and nonmetals, and molecular (or covalent) compounds are made of nonmetals. We'll learn how they bond differently: in covalent compounds, the atoms share electrons, and in ion compounds, atoms steal electrons and then opposite charges attract. Ionic and molecular (covalent) compounds also look different at the microscopic level: covalent and molecular compounds exist in molecules, while ionic compounds are organized in lattice structures.

Why is water essential for Life to exist on Earth? We are about 60% water - and there are some organisms that are as much as 90% water! What is so important about water? How does it support life? In this video, we discuss the special properties of water that make it the “Solvent of Life.” Chief among these properties is the extensive Hydrogen Bonding between water molecules that make water an extremely cohesive liquid (the molecules stick together). Due to the extensive hydrogen bonding, water has some emergent properties that impact life on Earth in many ways. These include: Cohesion Adhesion High surface tension High specific heat High heat of vaporization Ice Floats (Ice is less dense as a solid than liquid water) For each of these properties, we discuss how they impact living creatures on Earth. ❀❀❀❀❀❀❀❀❀❀ Our series on Biology is aimed at the first-year college level, including pre-med students. These videos should also be helpful for students in challenging high school biology courses. Perfect for preparing for the AP Biology exam or the Biology SAT. Also appropriate for advanced homeschoolers. You can also follow along if you are just curious, and would like to know more about this fascinating subject.

Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible. The nature of the bond between atoms is related to the distance between them and, like people, it also depends on how positive or negative they are. Unlike with human relationships, we can analyze exactly what makes chemical relationships work, and that's what this episode is all about. If you are paying attention, you will learn that chemical bonds form in order to minimize the energy difference between two atoms or ions; that those chemical bonds may be covalent if atoms share electrons, and that covalent bonds can share those electrons evenly or unevenly; that bonds can also be ionic if the electrons are transferred instead of shared: and how to calculate the energy transferred in an ionic bond using Coulomb's Law. -- Table of Contents Bonds Minimize Energy 01:38 Covalent Bonds 03:18 Ionic Bonds 05:37 Coulomb's Law 05:51 -- Want to find Crash Course elsewhere on the internet?

This chemistry video tutorial explains the difference between elements, atoms, molecules, and ions. It also explains how to distinguish ionic and molecular compounds also known as covalent compounds. Atoms are electrically neutral and contain equal number of protons and electrons. Ions have a net charge and contain a different number of protons and electrons. Positively charged ions are known as cations and negatively charged ions are known as anions. Atoms and Ions have the same number of neutrons. A molecule is particle consisting of multiple atoms. Pure elements are substances composed of one type of atom where as a compound is made up of different types of atoms. Ionic compounds consist of metals and nonmetals and contain ions with charges. Covalent compounds or molecular compounds usually consist of nonmetals.

Learn the basics about covalent bonds, when learning about properties of matter. When similar atoms react, like non-metals combining with other non-metals, they share electrons. This is covalent bonding. Non-metals have shells of electrons that are normally half or more than half full of electrons. Since they have a strong attraction for a few additional electrons, it is energetically unfavourable for any of them to lose electrons, so they share electrons by overlapping orbitals. This makes a bonding orbital, or covalent bond, that contains two or more electrons. Covalent bonds can be represented by a dot and cross diagram. These diagrams show only the valence electrons. Covalent bonds are directional, which means they are in a fixed position. The overlap between orbitals mean that the atoms in covalent bonds are very close, and make covalent bonds strong. There are two kinds of covalent structure - small molecules, like water, and giant compounds, like diamond. The electrons in the bonds are evenly shared, which means the bonds are not polarised; there is little attraction between molecules, and forces between molecules are weak. Compounds made from small covalent molecules have low melting and boiling points and are volatile. They also don’t conduct electricity. Carbon and silicon tend to form giant covalent compounds. These bond in the same way, but instead of forming small molecules with one or two bonds, they form four, make up huge lattices or chains of many many linked up atoms. Diamond is a common example, and is made up of Carbon. These compounds have very high melting and boiling points because you have to break covalent bonds rather than intermolecular forces to make them free enough to act like liquids or gases. The covalent bonds hold them rigidly in place in the giant lattice. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.

Water is made up of one oxygen atom, and two hydrogen atoms. And looks something like this. This structure makes water a very polar molecule. Without going into the beautiful details, Oxygen has a net negative charge while the opposite ends with the hydrogens have a net positive charge. This allows water molecules to form hydrogen bonds and gives water many of its other properties. Cohesion and Adhesion are two such properties. Cohesion is water’s attraction to itself. The hydrogen bonds that I mentioned facilitate this. This is also why water has surface tension, allowing bugs to walk on it. Additionally, cohesion keeps water a liquid at moderate temperatures instead of a gas. Adhesion is water’s attraction to other surfaces. Water will adhere to anything it can form a hydrogen bonds with. This is the reason for capillary action, where water climbs up a narrow glass tube. Another property of water is it’s high heat capacity. Heat capacity is a substance ability to absorb heat. More accurately, it’s the amount of energy needed to raise one gram of a substance by one degree celsius. This allows water to absorb temperature changes and keep air temperature at moderate levels. Which is pretty cool… Finally, water is known as the universal solvent, meaning that a wide range of substances can be dissolved in it. This includes hydrophilic and polar molecules like sugars and salts. Substances that generally don’t dissolve in water are hydrophobic, like oils. So now you know a little more about the properties of H2O, and bare in mind, we only covered a portion of water’s amazing properties, so be sure to check the links in the description to learn more.

Learn the basics about the covalent bonding of water, when learning about covalent bonding within properties of matter. Water is made from one oxygen atom and two hydrogens. The oxygen has 6 electrons in its outer shell, but it really wants to have 8 to have a full shell. The hydrogens have one outer shell electron, but want to have two. The atoms share their electrons, forming covalent bonds. So all three atoms have full outer shells, and create a water molecule. Water has two covalent bonds. In water, the bonding electrons spend most of their time nearer the oxygen atom, because it is more ELECTRONEGATIVE. This means that it is electron withdrawing. As the negatively charged electrons are nearer the oxygen atom, the oxygen atom becomes a little bit negative itself, while the hydrogens become a little positive. This is called delta positive and delta negative. Water doesn’t just have any old covalent bonds; it has what we call POLAR COVALENT bonds and is a POLAR molecule. This is really important as it affects how water behaves and reacts with other elements. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.

We'll learn how to write names for compounds that are made of two nonmetals, sometimes called binary compounds. Binary compounds made of two nonmetals are called covalent or molecular because the elements are held together with covalent bonds, and they make molecules. In order to name them, we use the element name for the first element in the chemical formula, and then we use the -ide name for the second name in the chemical formula. Greek prefixes to show the number of atoms of each element, and these are put in front of the element names.

*** PLEASE WATCH WITH ANNOTATIONS ON! SOME INACCURACIES IN GRAPHICS ARE NOTED AND CORRECTED IN ANNOTATIONS. THANKS! *** Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is polar or non-polar, which describes a kind of symmetry - not just of the molecule, but of the charge. In this edition of Crash Course Chemistry, Hank comes out for Team Polar, and describes why these molecules are so interesting to him. You'll learn that molecules need to have both charge asymmetry and geometric asymmetry to be polar, and that charge asymmetry is caused by a difference in electronegativities. You'll also learn how to notate a dipole moment (or charge separation) of a molecule, the physical mechanism behind like dissolves like, and why water is so dang good at fostering life on Earth. -- Table of Contents Charge Assymetry & Geometric Asymmetry 01:33 Difference in Electronegatives 01:49 Hank is Team Polar 00:33 Dipole Moment 03:49 Charge Separation of a Molecule 04:12 Like Dissolves Like 04:41 Water is Awesome 05:10 -- Want to find Crash Course elsewhere on the internet?

Covalent Bonding. Noble gases have complete outer electron shells, which make them stable. The coming together and sharing of electron pairs leads to the formation of a chemical bond known as a covalent bond. Two chlorine atoms come together and share their electrons to form a molecule of chlorine. In this way, each atom will have eight electrons in its valence shell. As a single pair of electrons is shared between them, the bond is known as a single covalent bond. A single covalent bond is represented by a single dash between the atoms. When two oxygen atoms come together, they each share 2 electrons to complete their octets. Since they share two pairs of electrons, there is a double bond between the oxygen atoms. Similarly, Nitrogen atoms share a triple covalent bond to form a molecule of Nitrogen.

This video looks at how to determine polarity in a molecule by understanding how the bond polarities, molecule shape, and outside atoms influence polarity using bond polarity vector addition. This includes a flow chart that guides you through the various decisions needed to determine if a molecule is polar or not. Wikipedia 1/1/2018: In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. A polar molecule with two or more polar bonds must have a geometry which is asymmetric in at least one direction, so that the bond dipoles do not cancel each other. While the molecules can be described as "polar covalent", "nonpolar covalent", or "ionic", this is often a relative term, with one molecule simply being more polar or more nonpolar than another. However, the following properties are typical of such molecules. A molecule is composed of one or more chemical bonds between molecular orbitals of different atoms. A molecule may be polar either as a result of polar bonds due to differences in electronegativity as described above, or as a result of an asymmetric arrangement of nonpolar covalent bonds and non-bonding pairs of electrons known as a full molecular orbital. Polar molecules The water molecule is made up of oxygen and hydrogen, with respective electronegativities of 3.44 and 2.20. The dipoles from each of the two bonds (red arrows) add together to make the overall molecule polar. A polar molecule has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from polar bonds arranged asymmetrically. Water (H2O) is an example of a polar molecule since it has a slight positive charge on one side and a slight negative charge on the other. The dipoles do not cancel out resulting in a net dipole. Due to the polar nature of the water molecule itself, polar molecules are generally able to dissolve in water. Other examples include sugars (like sucrose), which have many polar oxygen–hydrogen (−OH) groups and are overall highly polar. If the bond dipole moments of the molecule do not cancel, the molecule is polar. For example, the water molecule (H2O) contains two polar O−H bonds in a bent (nonlinear) geometry. The bond dipole moments do not cancel, so that the molecule forms a molecular dipole with its negative pole at the oxygen and its positive pole midway between the two hydrogen atoms. In the figure each bond joins the central O atom with a negative charge (red) to an H atom with a positive charge (blue). The hydrogen fluoride, HF, molecule is polar by virtue of polar covalent bonds – in the covalent bond electrons are displaced toward the more electronegative fluorine atom. Ammonia, NH3, molecule the three N−H bonds have only a slight polarity (toward the more electronegative nitrogen atom). The molecule has two lone electrons in an orbital, that points towards the fourth apex of the approximate tetrahedron, (VSEPR). This orbital is not participating in covalent bonding; it is electron-rich, which results in a powerful dipole across the whole ammonia molecule. Resonance Lewis structures of the ozone molecule In ozone (O3) molecules, the two O−O bonds are nonpolar (there is no electronegativity difference between atoms of the same element). However, the distribution of other electrons is uneven – since the central atom has to share electrons with two other atoms, but each of the outer atoms has to share electrons with only one other atom, the central atom is more deprived of electrons than the others (the central atom has a formal charge of +1, while the outer atoms each have a formal charge of −1⁄2). Since the molecule has a bent geometry, the result is a dipole across the whole ozone molecule. When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also known as the H-bond. For example, water forms H-bonds and has a molar mass M = 18 and a boiling point of +100 °C, compared to nonpolar methane with M = 16 and a boiling point of –161 °C. Nonpolar molecules A molecule may be nonpolar either when there is an equal sharing of electrons between the two atoms of a diatomic molecule or because of the symmetrical arrangement of polar bonds in a more complex molecule. Not every molecule with polar bonds is a polar molecule. Carbon dioxide (CO2) has two polar C=O bonds, but the geometry of CO2 is linear so that the two bond dipole moments cancel and there is no net molecular dipole moment; the molecule is nonpolar.

Effect of H-bond on physical properties of compounds : 1) Water is liquid at room temperature , while H2S (Hydrogen sulphide ) is a gas. Reason – Water molecules are associated through inter molecular H- bond .So molecules become closer to each other while in H2S , hydrogen bond is not present. So water is a liquid and H2S is a gas.

021 - Metallic Bonding In this video Paul Andersen explains how metallic bonding structure creates the different properties of metals. The electron sea model explains how the positive nuclei are locked into a negative sea of delocalized electrons. This sharing of electrons creates metals that are good conductors, malleable, ductile and non-volatile. A shell model can be used to explain certain properties of metals (like melting point).

Did you know that geometry was invented by molecules? It's true! Until the first stars went supernova and littered all the elements across the cosmos, everything was simply spheres, from protons to stars. But then, under cooler planetary conditions, atoms came together to form molecules, and in doing so, they created the first shapes the universe had ever seen.
