Nuclear Physics and RadioactivityHard

Question

Choose the CORRECT statement(s)

Options

A. Mass of products formed is less that the original mass in nuclear fission and nuclear reactions.
B.Binding every per nucleon increases in α - decay and β - decay
C.mass number is conserved in all nuclear reactions.
D.atomic number is conserved in all nuclear reactions.

Solution

Fusion and fission are always exothermic  and  &  decay will result in more stable product.
Mass number is conserved but atomic number is not conserved.   
, = M + 0 and A may not be equal to B + C
