Have you ever heard about the role of a neutron in an atom?

Yeah, I think it's the particle that helps keep the nucleus stable, right?

Exactly! Without neutrons, the protons would repel each other too much.

Root Explanation

Neutron → It is formed from the prefix "neutr-" (from Latin "neutrum", meaning neither) and the suffix "-on" (a suffix used in chemistry to denote particles). The word "neutron" refers to a particle that is neither positively nor negatively charged, hence the name.

Memory Tip

Think of 'neutr-' meaning 'neither' to remember that a neutron is a particle that has no charge.
