Which of the following is a diatomic element?

Explanation:
Diatomic elements are those that exist as molecules made of two atoms of the same element. Hydrogen is found as H2, a diatomic molecule, which is the common form of hydrogen gas. Helium, neon, and argon are noble gases and exist as single, unbonded atoms in the gas phase, not as diatomic molecules. So the diatomic element here is hydrogen, in the form of H2.
