Answer:
In the elementary state, hydrogen
exists in diatomic form i.e., as \[{{H}_{2}}(g)\] and the two hydrogen atoms
are linked to each other by single covalent bond (H?H). Since the bond
dissociation energy is very high\[(435.9\,\,kJ\,mo{{l}^{-1}})\] therefore,
bond cleavage is extremely difficult. As a result, elemental hydrogen is little
reactive at room temperature.
