Definition - What does Neutron mean?

A neutron is a subatomic particle found in the nucleus of atoms. Unlike protons or electrons, the neutron has no electrical charge and its mass is fractionally greater than that of a proton. The symbols used to represent a neutron are the letter ‘n’ or ‘n0’.

Safeopedia explains Neutron

Neutrons were first discovered in 1932. During the sixties and seventies, experiments conducted at the Stanford Linear Accelerator Center showed that neutrons were composed of still smaller particles known as ‘quarks’. One ‘up’ quark and two ‘down’ quarks form a neutron. Since neutrons are found in the nucleus of atoms together with protons, protons and neutrons are collectively termed ‘nucleons’.
