2h is a loosely bound isotope of hydrogen, called deuterium or heavy hydrogen. it is stable but relatively rare - it form only 0.015% of natural hydrogen. note that deuterium has z = n, which should tend to make it more tightly bound, but both are odd numbers.

2H consists of one proton and one neutron. The atomic mass of a proton is 1.00782u. The atomic mass of a neutron is equal to 1.00866u

Total mass=2.016u and mass of deuterium is equal to 2.01u

Mass difference = 0.002388u

BE = 0.002388 * (3*108) ²

=3.56912*10-13J

=2.230 Mev

=1.1153 Mev/nucleon
