When a uranium isotope ${}_{92}^{235}U$ is bombarded with a neutron, it generates ${}_{36}^{89}{Kr}$ , three neutrons and:NEET 2020 (Phase 1)

Options:

Answer:

Solution:

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

A = $235 - 89 - (3 \times 1) = 143$

Z = $92 - 36 = 56$

Hence, the element must be Barium.

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