Several experiments done by New Zealand physicist Ernest Rutherford established that an atom consists of a positively charged nucleus surrounded by a cloud of negatively charged electrons. According to Planck’s relation, when an electron moves from one orbit to another, it absorbs or emits radiation.ĭevelopment of the Bohr Model How is Bohr’s Atomic Model Different from Rutherford’s Model.The energy of the electron depends on the principal quantum number n.
Electrons orbiting in orbits do not interact with each other.Electrons move around the nucleus in orbits of well-defined radius.Bohr Model Salient Features of the Bohr Model
