When Uranium is bombarded with neutrons, it undergoes fission. The fission reaction can be written as :
$$\begin{array}{r}
{ }_{92} \mathrm{U}^{235}+{ }_0 \mathrm{n}^1 \rightarrow{ }_{56} \mathrm{Ba}^{141}+{ }_{36} \mathrm{Kr}^{92}+3 x \\
+\mathrm{Q} \text { (energy) }
\end{array}
$$
where three particles named $\displaystyle x$ are produced and energy Q is released. What is the name of the particle $\displaystyle x$ ?
Official answer
(3)
neutron
