Which of the following nuclear fragments corresponding to nuclear fission between neutron (01n)\left({ }_0^1 \mathrm{n}\right) and uranium isotope (92235U)\left({ }_{92}^{235} \mathrm{U}\right) is correct :

Options

  1. A56144Ba+3689Kr+401n{ }_{56}^{144} \mathrm{Ba}+{ }_{36}^{89} \mathrm{Kr}+4{ }_0^1 \mathrm{n}
  2. B56144Ba+3689Kr+301n{ }_{56}^{144} \mathrm{Ba}+{ }_{36}^{89} \mathrm{Kr}+3{ }_0^1 \mathrm{n}
  3. C56140Xe+3894Sr+301n{ }_{56}^{140} \mathrm{Xe}+{ }_{38}^{94} \mathrm{Sr}+3{ }_0^1 \mathrm{n}
  4. D51153Sb+4199Nb+301n{ }_{51}^{153} \mathrm{Sb}+{ }_{41}^{99} \mathrm{Nb}+3{ }_0^1 \mathrm{n}

Correct answer

B. 56144Ba+3689Kr+301n{ }_{56}^{144} \mathrm{Ba}+{ }_{36}^{89} \mathrm{Kr}+3{ }_0^1 \mathrm{n}

Step-by-step solution

Balancing mass number and atomic number 92235U+01n→56144Ba+3689Kr+301n{ }_{92}^{235} \mathrm{U}+{ }_0^1 \mathrm{n} \rightarrow{ }_{56}^{144} \mathrm{Ba}+{ }_{36}^{89} \mathrm{Kr}+3{ }_0^1 \mathrm{n}
