Niels Bohr. Adapted the nuclear model by suggesting that electrons orbit the nucleus at specific distances. James Chadwick. Provided the evidence to show the existence of neutrons within the nucleus.

WebAtoms range in size from a diameter of around 1x10 -10 m (0.1 nanometres) to 5x10 -10 m (0.5 nanometres ), while the nucleus has a diameter of around 1.75x10 -15 m (1.75 femtometres) to 15x10 -15 m (15 femtometres ). This means the nucleus is 100,000 times smaller than the atom. WebThe Nuclear Model was first proposed by Ernest Rutherford after he successfully disproved the Plum Pudding Model of the atom using his alpha scattering experiment. In the Nuclear Model most of the atom is empty space. The majority of the mass of the atom is concentrated in a small central nucleus.
