The isotopes of hydrogen are:

Options

  1. AProtium, deuterium and tritium
  2. BTritium and protium only
  3. CProtium and deuterium only
  4. DDeuterium and tritium only

Correct answer

A. Protium, deuterium and tritium

Step-by-step solution

Isotopes have same atomic number and different atomic mass i.e., Same number of proton different number of Neutron relative atomic mass Protium H 1 1 Deuterium H 2 1 Tritium H 3 1
