Atomic Models and Bohr's Theory

How our understanding of the atom's structure evolved.

Rutherford's Model

Rutherford's alpha-particle scattering experiment showed that an atom has a tiny, dense, positively charged nucleus, with electrons orbiting around it.

Bohr's Model

Bohr proposed that electrons orbit the nucleus only in certain fixed, quantized energy levels, without radiating energy while in these stable orbits.
