Diatomic Molecules are molecules that contains two atoms : H2, N2, O2, F2, Cl2, Br2, I2

Polyatomic Molecules are molecules that contains more than 2 atoms : P4, S8

H2O: can also be called HOH. H2O can also be called HOH because in some equations, they will use OH. Since to make balancing easier, HOH is use to make OH a whole instead of H and O.
