Question

Why does hydrogen occur in a diatomic form rather than in a monoatomic form under normal condi-tions ?​

Answer 1

Hydrogen has an electronic configuration of 1s1. Its outer shell is not complete. So, hydrogen forms covalent bond with another hydrogen atom which results in completely filled shell of electrons which is much more stable than half filled shell. Hence, hydrogen occurs in a diatomic form rather than in a monoatomic form under normal conditions.

The ionization enthalpy of hydrogen atom is very high (1312 kJ mol-1). 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.
