Question

In the nuclear chain reaction of uranium disintegration which of the

Answer 1

Answer: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.

Explanation:

Answer 2

Explanation:

A possible nuclear fission chain reaction. 1. A uranium-235 atom absorbs a neutron, and fissions into two new atoms (fission fragments), releasing three new neutrons and a large amount of binding energy. ... One of those neutrons is absorbed by an atom of uranium-238, and does not continue the reaction.
