Question

In a nuclear fission reaction, the mass of the original nucleus is:

• A. Just little more than the sum of the masses of the individual products.
• B. Just equal to the sum of the masses of the individual products.
• C. Just little lesser than the sum of the masses of the individual products.
• D. Not comparable with individual masses of the products.

Answer 1

The correct option is A

Just little more than the sum of the masses of the individual products.

In a nuclear fission reaction, the mass of the original nucleus is a just little more than the sum of the masses of the individual products. In nuclear fission, the nucleus of a heavy atom when bombarded with low energy neutron split (break down) into lighter nuclei and a huge amount of energy is being released.
