Q. If $M_{0}\ $is the mass of an oxygen isotope $\ _{8}O^{17}$ , $M_{p}and\ M_{n}are\ the$ masses of a proton and a neutron, respectively, the nuclear binding energy of the isotope is
A) $\left( M_{o}\ –\ 8M_{p} \right)c^{2}$
B) $\left( M_{o}\ –\ 8M_{p}\ - 9M_{n} \right)c^{2}$
C) $M_{o}c^{2}$
D) $\left( M_{o}\ –\ 17\ M_{n} \right)c^{2}$
Explanation
(b) Binding energy
$BE = \ \left( M_{nucleus} - \ M_{nucleons} \right)c^{2}\ = \ \left( M_{o} - 8M_{p} - 9M_{n} \right)c^{2}$
