Answer:

Diatomic elements are a subgroup of diatomic molecules.

Explanation:

Every molecule that consists of two atoms is diatomic. Only if the two atoms are the same there is a diatomic element.

So #O_2# is a diatomic element (and thus a diatomic molecule)
#HCl# is a diatomic molecule, but not a diatomic element.
