The number of beta particles emitter by ...

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

isomer of parent

B

isotone of parent

C

isotope of parent

D

isobar of parent

Text Solution

Verified by Experts

The correct Answer is:
C
`"" _(Z) ^(A)X overset(2 beta ^(-))to Z +2 "" ^(A) Y _(1) overset(alpha ) to "" ^(A -4) Z _(Y _(2))`
The resultant daughter is an istope of the original parent nucleus.
