When 92 U 235 is bombarded with one neutron, fission occurs and the products are three neutrons, 36 K r 94 , and

Options

  1. A56 B a 141
  2. B54 X e 139
  3. C56 B a 139
  4. D58 I 142

Correct answer

C. 56 B a 139

Step-by-step solution

When a slow neutron strikes a U 235 nucleus it is absorbed by the nucleus and the following reaction occurs. 92 U 235 + 0 n 1 → 36 K r 94 + 56 B a 139 + 3 0 n 1 + e n e r g y Hence, 56 B a 139 is another product.
