A nucleus `._n X^m` emits one `alpha` and one `beta` particles. The resulting nucleus is.

A

`._n X^(m-4)`

B

`._(n -2) Y^(m - 4)`

C

`._(n -4) Z^(m -4)`

D

`._(n -1) Z^(m -4)`

Text Solution

Verified by Experts

The correct Answer is:

D

(d) `._n X^m overset (alpha)rarr ._(n -2)X^(m -4) overset (-beta)rarr ._(n-1) X^(m-4)`.
