Nuclear Fission & Fusion

When a uranium isotope ${}^{235}_{92}U$ is bombarded with a neutron, it generates ${}^{89}_{36}Kr$ , three neutrons and:

Show answer and solution

Answer: (d)

${}^{235}_{92}U + {}^{1}_{0}n \to {}^{89}_{36}Kr + 3\,{}^{1}_{0}n + X$
$A = 236 - 89 - 3 = 144$ , $Z = 92 - 36 = 56$
So the answer is (d) ${}^{144}_{56}Ba$ .
