Find the energy needed to remove a proton from nucleus.

Open in App

Solution

Energy needed to remove a proton from nucleus $= △ m c^{2}$
$△ m =$ mass of nucleus $-$ mass of proton
= (mass of neutron + mass of proton) - mass of proton
= mass of neutron
= 1.008665amu
$E = 1.008665$ X $931 = 939.067 M e V$
