Deuterium is less reactive than Hydrogen.

Deuterium, ($D$ or ${}^{2}H$), also called heavy hydrogen, isotope of hydrogen with atomic weight of approximately 2. Its nucleus, consisting of one proton and one neutron, has double the mass of the nucleus of ordinary hydrogen. Deuterium, reacts more slowly than ordinary hydrogen, It is due to relatively stronger D-D bond. Its a criterion that distinguishes the two forms of hydrogen.
