Practicing Success
When $U^{235}$ is bombarded with one neutron, the fission occurs and the products are three neutrons, ${ }_{36} \mathrm{Kr}^{94}$ and |
${ }_{53} I^{142}$ ${ }_{56} B a^{139}$ ${ }_{58} C e^{139}$ ${ }_{54} X e^{139}$ |
${ }_{56} B a^{139}$ |
${ }_0 n^1+{ }_{92} U^{235} \rightarrow{ }_{36} K r^{94}+{ }_{56} B a^{139}+3{ }_0 n^1$ |
