iv.5. J. Chadwick Neutron: Bridging the Mass Balance in Atomic Structure
Chadwick’s Neutron Discovery |
Neutral Force in Atomic Structure: In 1932, J. Chadwick discovered another subatomic particle which had no charge and a mass nearly equal to that of a proton named as neutron (represented as ‘n’). |
Elemental Presence, Excluding Hydrogen |
Neutrons are present in the nucleus of all atoms, except hydrogen. |
Mass Calculation in Atoms |
The mass of an atom is therefore given by the sum of the masses of protons and neutrons present in the nucleus. |
