Ionic Compounds and Molecules
What's an Ion? by Tyler DeWitt [6:52]Confused about ions? We'll learn the difference between an atom and an ion. Ions are formed because of a net charge on an atom, because the number of protons and electrons do not balance. This means that the atom is no longer electrically neutral, but is a cation or an anion. We also talk about polyatomic ions.
Ionic vs. Molecular by Tyler DeWitt [8:52]
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.
Ionic Bonding Introduction by Tyler DeWitt [7:20]
This video is an introduction to ionic bonding, which is one type of chemical bonding. Ionic bonds hold together metal and nonmetal atoms. In ionic bonding, electrons are transferred from a metal atom to a nonmetal atom, creating ions. These ions have opposite charge, so they stick together.
Valence Electrons and the Periodic Table by Tyler DeWitt [16:53]
Where do electrons live in atoms? They live in energy levels or shells, which are varying distances from the nucleus, and can hold varying numbers of electrons. The most important electrons in an atom are the valence electrons, which are in the outermost energy level or shell. We'll look at how to determine the number of valence electrons in an atom, based on which column it is in on the periodic table.
Ionic Bonding Part 2 by Tyler DeWitt [10:17]
We'll look at the details of ionic bonding, using sodium chloride as an example. Both atoms have unfilled valence shells, which are the outermost energy level. Electrons are transferred from the metal to the nonmetal, creating ions with an opposite charge. The atoms are then held together because of the attraction between the opposite charges.
Ionic Bonding Part 3 by Tyler DeWitt [7:57]
Here, we'll talk about electronegativity, and why some atoms steal electrons, while other atoms give them away. We will look at the 3D lattice structures that are formed during ionic bonding, and we'll have a quick introduction to writing chemical formulas and naming ionic compounds.
Ionic Bonding FAQ: Valence Electrons 1 by Tyler DeWitt [1:18]
We discuss commonly asked questions about ionic bonding and valence electrons.

Writing Ionic Formulas: Introduction by Tyler DeWitt [11:44]
Here's how to write formulas for binary ionic compounds. We'll see how you have to balance the charges of the two ions so they cancel each other out.
Writing Ionic Formulas: Practice Problems by Tyler DeWitt [3:42]
Lots of practice problems for writing formulas of ionic compounds, so you can get really good at this. In order to write an ionic formula, the charges of the positive ion (cation) and the negative ion (anion) have to balance each other out so that the compound is neutral.
