A nucleus decays by `beta^+` emission followed by a gamma emission. If the atomic and mass numbers of the parent nucleus are `Z` and `A` respectively, the corresponding numbers for the daughter nucleus are respectively.

A

`Z - 1 and A - 1`

B

`Z + 1 and A`

C

`Z - 1 and A`

D

`Z + 1 and A - 1`

Text Solution

Verified by Experts

The correct Answer is:
C
( c) After `beta^+(._(+ 1) e^0)` emission atomic number decreases by one and mass number remain unchanges. `gamma-`emission, there will be no change on mass number and atomic number.
