Which one of the following is a possible nuclear reaction ?

Options

A. `""_5B^10 + ""_2He^4 to ""_7N^13 + ""_1H^1`
B. `""_11Na^23 + ""_1H^1 to ""_10N^20 + ""_2He^4`
C. `""_93Np^239 to ""_94 Pu^239 + ""_(-1)e^0`
D. `""_7N^11 + ""_1H^1 to ""_6 C^12 + ""_(-1)e^0`

Answer

C

Explanation

In a nuclear reaction, the charge and mass are conserved
Only in (c ) both are conserved.
Thus charge `to` 93 = 94 - 1 = 93
Mass `to` 239 = 239 + 0 = 239
In a , b and d charge and mass are not conserved
