millikan model of an atom

Atomic Models..

'Raisin Pudding' Model - Thomson's model of atom : J. J Thomson the discoverer of the electron believed that the atom is a uniform sphere of positive charge with electrons (raisins) embedded in i..

Two new theories came to substantially modify Bohr's Atomic model. They a..

Rutherford's model had a major drawback. It could not explain why ultimately electrons did not fall into the nucleus by taking a spiral path. This was in concurrence with the electromagnetic theory that states 'if a charged particle undergoes accelerated motion then it must radiate energy..

In 1913, Neils Bohr proposed a model of an atom based on the Planck's quantum theory of radiation. The basic postulates of Bohr's theory are: * An atom consists of a small, heavily positively charged nucleus around which electrons revolve in definite circula..

J. J Thomson, the discoverer of the electron believed that the atom is a uniform sphere of positive charge with electrons (raisins) embedded in it. This model explained the electrical neutrality of atom, but it failed to explain how these fundamental particles were ar..
