Neutron — Science definition
Defined in 2 courses:
- A particle with no charge (neutral) found in the nucleus, alongside the protons. (Physical Science: Matter, Forces & Energy)
- An electrically neutral subatomic particle in the nucleus, with a relative mass of about 1 amu. (Physical Science: Chemistry)
