The atomic concept of matter was put forward by Dalton to explain the laws of chemical combination. Rutherford proposed that the atoms contain a positive centre called nucleus around which the electrons are revolving in circular paths. This model however could not explain the stability of atom and atomic spectrum of hydrogen and was modified by Bohr who treated the electrons as particles and assigned to them definite circular paths called orbits around the nucleus. However Bohr’s idea of well-defined orbits came in direct conflict with modern principles such as dual nature of matter, which considers electrons as particles as well as waves, and Heisenberg’s uncertainty principle according to which it is not possible to find out position and momentum of a small particle such as electron with absolute accuracy.
