The ionization enthalpy of hydrogen is very high (1312kJ mol^(-1)). Hence, it is very hard to remvoe its only electron. As a result, its tendency to exist in the monoatomic form is rather low. Istead, hydrogen forms a covalent bond with another hydrogen atom and exists as a diatomic (H_(2)), molecule.
