A nucleus \(_z^{A} X\) has a mass represented by M(A, Z). If Mp and Mn denote the mass of proton and neutron respectively and B.E. the binding energy in MeV, then
- B.E. = [ZMp + (A − Z)Mn − M(A, Z)]c2
- B.E. = [ZMp + AMn − M(A, Z)]c2
- B.E. = M(A, Z) − ZMp − (A − Z)Mn
- B.E. = [M(A, Z) − ZMp − (A − Z)Mn]c2
Answer
(A) B.E. = [ZM p + (A − Z)M n − M(A, Z)]c 2
