Explanation:
Detailed explanation-1: -Diatomic hydrogen has a formula of H2. It is also called hydrogen gas. It is a stable molecule. It consists of two hydrogen atoms bound together (thus, the name).
Detailed explanation-2: -The ionization enthalpy of hydrogen atom is very high (1312 kJ mol−2). Hence, it is very hard to remove its only electron. As a result, its tendency to exist in the monoatomic form is rather low. Instead, hydrogen forms a covalent bond with another hydrogen atom and exists as a diatomic (H2) molecule.
