    Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.

    After the discovery of electrons and protons,it was noticed that all mass of an atom cannot be accounted for on the basis of only protons and electrons.Then the neutrons were discovered.

    Chadwick in 1932 discovered another subatomic particle called neutron.
    Neutron is present inside the nucleus.
    Hydrogen atom does not contain any nucleus.

    Characteristics of neutron
    1)The mass of neutron is equal to mass of proton.The relative mass of neutron is 1 u and absolute mass is 1.6749 x 10-27 kg.

    2)Neutron has no charge.
