The properties of electrons, protons and neutrons-
Practile | Nature of Charge | Mass | Location |
---|---|---|---|
Electron | Electrons are negatively charged. | \(9 \times 10^{–31}\) kg | Extra nuclear part distributed in different shell or orbits. |
Proton | Protons are positively charged. | \(1.672 \times 10^{–27}\) kg (1 µ) (approx. 2000 times that of the electron) | Nucleus |
Neutron | Neutrons are neutral. | Equal to mass of proton | Nucleus |
