Question

As the mass number A increases, the binding energy per nucleon in a nucleus
(a) increases
(b) decreases
(c) remains the same
(d) varies in a way that depends on the actual value of A.

Answer 1

Explanation:

Binding energy per nucleon is obtained by dividing the binding energy with mass number and is the measure of the stability of nucleus. The binding energy per nucleon is less for lighter nuclides and increase with the mass number.

Answer 2

mass is inversly proprtional to binding energy per nucleon so as mass increases binding energy per nucleon decreases
