A nucleus decays by β+\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

Z1Z - 1 and A1A - 1

B

Z+1Z + 1 and AA

C

Z1Z - 1 and AA

D

Z+1Z + 1 and A1A - 1

Answer

Z1Z - 1 and AA

Explanation

Solution

After β+(+1e0)\beta^{+}(_{+ 1}e^{0}) emission atomic number decreases by one and mass number remain unchanged. γ-emission, there will be no change on mass number and atomic number.
