Q. In the following nuclear reaction $\ _{6}C^{11} \rightarrow {\ _{5}B}^{11} + \beta^{+} + X$ What does $X$ stand for?

A) A neutron
B) A neutrino
C) An electron
D) A proton
Explanation

(b) The nuclear reaction can be put as
$\ _{6}C^{1} \longrightarrow_{5}B^{11} +_{+ 1}e^{0} +_{z}X^{A}$
Applying conservation of mass number and charge number, we find that
$A = 0$ and $Z = 0$
Therefore, $X$ stands for a neutrino
