Which of the following nuclear reaction is not possible?

Options

A. `""_3^7Li + ""_2^4He to ""_1^1H + ""_4^10B`
B. `""_6^12 C + ""_6^12C to ""_10^20 Ne + ""_2^4 He`
C. `""_4^9Be + _1^1H to ""_3^6 Li + ""_2^4 He`
D. `""_5^11Be + ""_1^1 H to ""_4^9 Be + ""_2^4 He`

Answer

D

Explanation

In all nuclear reactions both charge (atomic number ) and mass number (A) are conserved
This condition is satisfied in (a), (b) and (c ).
But in (d) 11 + 1 `ne` 9 + 4 ( mass numbers are not equal). Hence this reaction is not possible .
