Neutron is a fundamental particle which is essential constituent of all nuclei except that of hydrogen atom. It was discovered by Chadwick. A free neutron outside the nucleus is unstable and decays into proton and electron.
\[_{0}{{n}^{1}}\,\,\to \,\,\underset{\text{Proton}}{\mathop{_{1}{{H}^{1}}}}\,\,\,+\,\,\underset{\text{Electron}}{\mathop{_{-1}{{\beta }^{0}}}}\,\,\,+\,\,\underset{\text{Antinutrino}}{\mathop{{\bar{\nu }}}}\,\]
(1) The charge of neutron : It is neutral
(2) The mass of neutron : \[1.6750\times {{10}^{-27}}\,kg\]
(3) It's spin angular momentum : \[\frac{1}{2}\times \left( \frac{h}{2\pi } \right)\,J\text{-}s\]
(4) It's magnetic moment : \[9.57\times {{10}^{-27}}\,J/Tesla\]
(5) It's half life : 12 minutes
(6) Penetration power : High
(7) Types : Neutrons are of two types slow neutron and fast neutron, both are fully capable of penetrating a nucleus and causing artificial disintegration.
