In this article, we’re going to go over how to convert basic chemical formulas, such as C9H804 (aspirin), into its molecular structure, and visa versa. Such knowledge might be elementary ...

For example, magnesium oxide is made up of two elements, magnesium and oxygen. Its formula is MgO. This shows that it has one atom of magnesium for every one atom of oxygen.

It's important to remember which elements exist as molecules, and which do not. Take care to use the correct form in chemical equations involving these elements.

Chemical formulas are actually taught in chemistry classes, where they are systematically introduced at the junior level. In ...
