When looking at binary compounds that are made up of only nonmetals that are also called molecular compounds you have to name them in the proper way and you also have two write the formula in a...
The chemical form the we found in less video is called the empirical formula the empirical formula is the simplest ratio of the elements that make up the formula in this case the simplest ratio is...
Let's take a look at the molecular geometry and bond angles for AsF5. We'll start by looking at the Lewis structure for AsF5. We have an Arsenic atom surrounded by 5 Fluorine atoms. We...
Hey guys, so the purpose of this screencast is to express the fundamental differences between ionic vs. molecular compounds and I picked just two examples here. Here is an ionic compound known as...
