- Get ready for an imperfect analogy. Imagine going to an ice cream store. Let's say that they have 30 different flavors of ice cream. Those are elements, the things that I have available to build my dessert from. The smallest amount of ice cream that the store will sell to me is a scoop. This is an atom. If I want, I can put two or more scoops of ice cream together. This is a molecule. If my molecule has more than one flavor of ice cream, I can call it a compound. So, in summary: element - a basic substance that can't be simplified (hydrogen, oxygen, gold, etc...) atom - the smallest amount of an element molecule - two or more atoms that are chemically joined together (H2, O2, H2O, etc...) compound - a molecule that contains more than one element (H2O, C6H12O6, etc...)
