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

Question

Aicharya · Accepted Answer

Let mass number & atomic number of the unknown element be A & Z.

A = $235 - 89 - (3 \times 1) + 1 = 1434$

Z = $92 - 36 = 56$

Hence, the element must be Barium.

${}_{92}^{235}U +_{0}^{1} n \to {}_{36}^{89}{Kr} + {}_{56}^{144}{Ba} + 3_{0}^{1} n + Q$
