To find the nuclear binding energy of the isotope ^{12}_{5}B, we need to first understand the components involved. The nuclear binding energy is the energy required to separate an atomic nucleus into its individual protons and neutrons. It can be calculated using the mass defect, which is the difference between the sum of the masses of the individual nucleons and the actual mass of the nucleus.
Therefore, the correct option that represents the nuclear binding energy of the isotope \(^{{12}}_{{5}}B\) is:
\((5M_p + 7M_n - M_0)C^2\)
The binding energy (\(B.E.\)) of a nucleus is given by:
\[B.E. = \Delta m c^2,\]
where \(\Delta m\) is the mass defect.
The mass defect for the isotope \({}^{12}_5 B\) is:
\[\Delta m = (5M_p + 7M_n) - M_0.\]
Substituting \(\Delta m\) into the binding energy equation:
\[B.E. = (5M_p + 7M_n - M_0)c^2.\]
Thus, the nuclear binding energy of the isotope is:
\[B.E. = (5M_p + 7M_n - M_0)c^2.\]
