Chemistry is about how atoms and molecules interact; psychology for molecules. It is a crossroads between biology and geology and it uses physics to describe the models of the atom and molecules.

Chemistry defines elements by the number of protons they have:
1 proton = hydrogen
2 protons = helium
3 protons = lithium
4 protons = beryllium
5 protons = boron
6 protons = carbon
7 protons = nitrogen
8 protons = oxygen

That's the first eight and most important to us as a large chunk of biology uses carbon, oxygen, nitrogen and hydrogen.
Oil is essentially different combinations of Carbon and Hydrogen. Whilst alcohol is composed of carbon, hydrogen and oxygen.
All you mention are molecules, atoms have only tree building stones.
