JEE Main 2024 — 4 April, Shift 1 — Question 33

Which of the following nuclear fragments corresponding to nuclear fission between neutron $\left({ }_{0}^{1} \mathrm{n}\right)$ and uranium isotope $\left({ }_{92}^{235} \mathrm{U}\right)$ is correct:

Option A:
${ }_{56}^{144} \mathrm{Ba}+{ }_{36}^{89} \mathrm{Kr}+4_{0}^{1} \mathrm{n}$
Option B:
${ }_{56}^{140} \mathrm{Xe}+{ }_{38}^{94} \mathrm{Sr}+3{ }_{0}^{1} \mathrm{n}$
Option C:
${ }_{51}^{153} \mathrm{Sb}+{ }_{41}^{99} \mathrm{Nb}+3{ }_{0}^{1} \mathrm{n}$
Option D:
${ }_{56}^{144} \mathrm{Ba}+{ }_{36}^{89} \mathrm{Kr}+3{ }_{0}^{1} \mathrm{n}$
Correct

Answer: D

Step-by-step solution

Balancing mass number and atomic number ${ }_{92}^{235} \mathrm{U}+{ }_{0}^{1} \mathrm{n} \rightarrow{ }_{56}^{144} \mathrm{Ba}+{ }_{36}^{89} \mathrm{Kr}+3{ }_{0}^{1} \mathrm{n}$
