For a neutral

^7\text{Li}

atom, the atomic mass is

7.016004\,\text{u}

. Take

m_p = 1.007276\,\text{u}

m_n = 1.008665\,\text{u}

m_e = 0.000548\,\text{u}

and

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

. (i) Calculate the mass defect of the

^7\text{Li}

nucleus in atomic mass units. (ii) Determine the binding energy per nucleon of

^7\text{Li}

in MeV.
