Answer-

The ionization enthalpy of the H-H bond is very high (1312kJ/mol). It means hydrogen has less tendency to form H^{+} ions. Its ionization enthalpy is comparable to halogens. Hence it forms a diatomic molecule, hydrides with the elements, and a large number of covalent bonds. It does not possess any metallic character like metals
