Deuterium (

^{2}_{1}\text{H}

) consists of one proton and one neutron. Its atomic mass (including one electron) is

2.014102\,u

. (i) What is meant by the term mass defect of a nucleus? (ii) Using

m_{p}=1.007276\,u

m_{n}=1.008665\,u

and electron mass

0.0005486\,u

, calculate the binding energy per nucleon of the deuterium nucleus. Use

1\,u=931.5\,\text{MeV}/c^{2}

. Show all steps clearly.
