# What is the difference between neutrons and neutrinos?

Apr 16, 2016

Neutrons are a type of nucleon, meaning they are found in the nucleus. They are also a baryon, since they are composed of three quarks: one up and two down. The neutron has a total charge of $0$, and a mass of just over $1$ atomic mass unit, or about $1.675 \cdot {10}^{-} 27 k g$, which is quite large as far as particle physics is concerned.
