Neutrons
Neutrons
Neutrons (/ˈnjuːtrɒn/) are subatomic particles, symbol n or n0, with no net electric charge and a mass slightly greater than that of a proton.
Etymology
The term "neutron" comes from the Latin root "neutr-", meaning "neutral", and the Greek suffix "-on", used in names of particles. It was coined by English physicist James Chadwick who discovered the neutron in 1932.
Properties
Neutrons are found in the nucleus of an atom, along with protons. They are a key component of atomic structure and play a crucial role in the stability of the nucleus. Neutrons are also involved in various types of nuclear reactions, including nuclear fission and nuclear fusion.
