Question

In nuclear fission the nucleus is divided into two or more fragments, releasing1) protons and energy.2) neutrons and energy.3) ions and energy.4) electrons and energy.

Answer 1

2) neutrons and energy.

Step-by-step explanation

Nuclear fission is a reaction whereby a heavy nucleus is bombarded by neutrons causing it to become unstable resulting in its splitting into two or more nuclei.

This reaction results in the production of kinetic energy, gamma particles (radiation), and neutrons (free neutrons).

Therefore, the correct option is option 2.
