Choose the CORRECT statement(s)

Options

A. Mass of products formed is less than the original mass in nuclear fission and nuclear fusion reactions.
B. Binding energy per nuclear increases in `alpha`-decay the `beta`-decay.
C. Mass number is conserved in all nuclear reactions.
D. Atomic number is conserved in all nuclear reactions.

Answer

A, B, C

Explanation

Fusion and fission are always exothermic and `alpha` & `beta` decay will result in more stable product.
`._(A)^(N)X rarr ._(B)^(M)Y + ._(C)^(0)Z,N = M+0` and `A` may not be equal to `B + C`
