Question

An important aspect of fission reactions is that they produce _______________ which allow for chain reactions.

Answer 1

Answer:

B. neutrons

Explanation:

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.

Answer 2

Answer:

B) neutrons

Explanation:

Fission reactions split large nuclei and release neutrons. The released neurons can then split another nucleus and the reaction can continue.
