Question

What is the reactivity order of isotopes of hydrogen?

Answer 1

There are three isotopic forms of hydrogen: Protium (H), Deuterium (D), Tritium (T). 

The isotopes of hydrogen show similar chemical properties since they possess same electronic configuration. But they show different physical properties due to different masses. However, the reactivity of protium is more than that of deuterium or tritium. It is due to relatively stronger D-D or T-T bond.
