Neutron is a fundamental particle which is necessary constituent of all nuclei except that of hydrogen molecule. It was discovered by Chadwick.
(1) The charge of neutron: It is neutral
(2) The mass of neutron: 1.6750 × 10-27 kg
(3) Its magnetic moment: 9.57 ×10-27 J/Tesla
(4) Its half life: 12 minutes
(5) Penetration power: High
(6) Types: there are two types of neutron slow neutron and fast neutron; both are fully capable of penetrating a nucleus and causing artificial disintegration.
