Solution

Definition of isotopes.
Isotopes are the atoms of the same element which have the same atomic number but a different mass number.
They have similar chemical properties and different physical properties.
Therefore isotopes of hydrogen are protium ( ${}_{1}^{1}H$ ),deuterium ( ${}_{1}^{2}H$ ),Tritium ( ${}_{1}^{3}H$ ).
