In this video we are going to look how to name binary ionic compounds. These compounds deal with the ionic bonding of 2 different elements. Remember that an ionic compound is formed between a metal and a nonmetal or a cation and an...

In this video, we're going to learn about the number of p, n and e in an atom. We'll explore the atomic structure of different elements, and see how the number of protons, neutrons and electrons affects the properties of those...

In this video, we're going to show you how to balance chemical equations – it's going to be easy! We'll start with the basics, and then move on to more complex problems. By the end of this video, you'll be able to balance chemical...

Writing formulas for ionic compounds is all about canceling out the charges! An ionic compound is formed between a cation and an anion, or a positive and negative charge so the goal is to always get the charges to add up to zero! In this...
