Rutherford Model<br />

BOHRS ATOM<br />

In 1913 Niels Bohr created a new model of the atom: The orbits of the electrons can’t<br />

be just anywhere but are “quantified”; When an electron jumps from one orbit to<br />

another it gives out energy as light giving rise to a spectrum.<br />

DISCOVERY OF NUCLEON<br />

Rutherford understood that the nucleus is itself composed of nucleons. These nucleons<br />

are of two types:<br />

Positively charged, it’s a proton. Neutrally charged, it’s a neutron. The neutron was<br />

effectively discovered in 1932 by Chadwick.<br />

Later we have added a large number of particles which make proton and neutrons and<br />

even electrons.<br />
