Bohr`s atomic model
... Bohr’s model cannot explain everything about atoms and line spectra and it has been superseded by more sophisticated models, but it was a major advance in atomic theory and quantum mechanics. In 1922 Bohr received the Nobel prize for physics. In a long working life at Copenhagen University he develo ...
