1. Monatomic Ions: Definition & Naming Convention
In this lesson, discover what it means to be a monatomic ion and learn some helpful examples. Then you will learn the naming convention for monatomic ions.

2. Naming Ionic Compounds: Simple Binary, Transition Metal & Polyatomic Ion Compounds
An important part of dealing with chemical compounds is knowing how to refer to them. Learn how to name all ionic compounds, including simple binary compounds, compounds containing transition metals and compounds containing polyatomic ions.

3. Writing Ionic Compound Formulas: Binary & Polyatomic Compounds
In this lesson, you will learn how to write the chemical formulas for both binary ionic compounds and polyatomic ionic compounds when you are given only the name of the compound. You will see that it is actually quite simple when you learn the steps described in this lesson.

4. Covalent Compounds: Properties, Naming & Formation
Learn about covalent bonds, how covalent compounds are formed and the properties inherent to covalent compounds, such as low melting and boiling points, in this lesson. Also, learn what rules to follow to name simple covalent compounds.

5. Formula Mass of a Compound: Definition & Formula
You can't put a molecule on a scale to determine its mass, so how can you figure it out? This lesson will give you the steps you need to calculate the formula mass of a compound and then will briefly discuss mass spectroscopy.

6. Calculating Percent Composition and Determining Empirical Formulas
Learn the difference between the empirical formula and chemical formula. Learn how to calculate the percent composition of an element in a compound. Learn how, if given a percent composition, to determine the empirical formula for a compound.
