Which element an atom is depends on the number of protons in the atoms nucleus. For example all hydrogen atoms have one proton and all oxygen atoms have 16 protons. Only about 25 different elements are found in organisms.

Atoms of different elements can link or bond together to form compounds. Atoms form bonds in two ways. All atoms of a specific element have the different chemical makeup size and mass.

Molecule is used to describe any atoms that are together by a chemical bond. Every compound is a molecule and every molecule is a compound. When elements join and become compounds they do not lose many of their individual behaviors.
