Question

The number of beta particles emitter by radioactive sustance is twice the number of alpha particles emitter by it. The resulting daughter is an
A. Isotope of parent
B. Isobar of parent
C. Isomer of parent
D. Isotone of parent

Answer 1

Correct Answer - A
`""_(Z)X^(A) overset(alpha)to ""_(Z-2)Y^(A-4) overset(2 beta) to ""_(Z)P^(A-4)`
As the resulting daughter and parent nucleus has same atomic number. So they are isotope.
