The number of beta particles emitter by radioactive sustance is twice the number of alpha particles emitter by it. The resulting daughter is an

Options

A. isobar of parent
B. isomer of parent
C. iostone of parent
D. isotope of parent

Answer

D

Explanation

Let the radioactive substance be `_(Z)^(A)X` Radioactive transition is given by
`_(Z)^(A)Xoverset(-alpha)to""_(Z-2)^(A-4)Xoverset(-2beta)to""_(Z)^(A-4)X`
So, `_(Z)^(A)Zand_(Z)^(A-4)X` are isotoppes.
