Element | Only contain one type of atom |
Compound | Two or more different elements combined |
Molecule | The smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms; a group of like or different atoms held together by chemical forces. A small particle; a tiny bit. |
