Some of the important postulates of the Bohr’s model of the atom were that the electrons moved around the nucleus in specified orbits. In these orbits they can move without radiating energy.

They can acquire or lose energy only in discrete units called quanta. Thus Bohr suggests that electrons in the atom exist in discrete (or quantized) energy states.

In 1902, Max Planck was able to show that experimental observations in the radiation emitted by substances could be explained on the basis that…
