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.
