Question

The products of the fission of $U^{235}$ by thermal neutron are

• A. $Ba^{141}$ and $Kr^{92}$ and 3 neutron always
• B. $Xe^{140},Sr^{94}\,and\, 2 \,_0n^1$ always
• C. can be different in each fission
• D. should have same mass number

Answer 1

Answer: (C)

$U^{235} \to {}_{56}^{144}Ba + {}_{36}^{89} Kr + 3 {}_{b}^{1}n$
$U^{235} + {}_{0}^{1} n \to U^{236} \to {}_{51}^{183}Sb + {}_{41}^{99}Nb + 4{}_{0}^{1}n$
