Why does hydrogen occur in a diatomic fo | Class 11 Chemistry Chapter Hydrogen, Hydrogen NCERT Solutions

Question:

Why does hydrogen occur in a diatomic form rather than in a monoatomic form under normal conditions?

Answer:

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.
