Bohr-1922 |
He mathematical worked out a model of a hydrogen atom. This explained the emission line spectrum of only certain wavelengths
(certain colours) using Planck's quantum concept. The Bohr atom Model: electron energy levels are fixed at certain amounts
or distances from nucleus; electron transitions from higher to lower levels result in separate wavelengths of emitted light.
Bohr conjectured that an atom could exist only in a discrete set of stable energy states. |
