Question

What is nuclear fission? Why is fission not self-sustaining chain reaction? Explain what is done to obtain chain reaction?

Answer 1

The answer is .......

When a free neutron hits the nucleus of a fissile atom like uranium-235 (235U), the uranium splits into two smaller atoms called fission fragments, plus more neutrons. Fission can be self-sustaining because it produces more neutrons with the speed required to cause new fissions. This creates the chain reaction.....................plzz MARK IT AS BRAINLIST
