PPT-Vector atom model Dr. Mahender

Singh Associate Professor in Physics PGGC 11 Chandigarh Vector model of an atom The total angular momentum of an atom result from the combination of the orbital and spin angular momenta of its electrons Angular momentum is a vector quantity so we can represent the total angular momentum by means of a vector J obtained by the addition of orbital angular momentum L and spin angular momentum S vectors This leads to the vector atom model . limits on . dark . energy.

J.J. Thomson. (1856-1940) . . In 1897 J.J. Thomson discovered the . electron. . This is a tiny negatively charged particle that is much, much smaller than any atom. He said that the tiny negatively charged electrons must be embedded in a cloud of positive charge. Thomson imagined the electrons as the bits of plum in a plum pudding, rather like currants spread through a Christmas pudding.. Known as the “Laughing Philosopher”. “Nothing exists except atoms and empty space; everything else is opinion.”. Created term “. atomos. ” which literally means “not cut” or indivisible.
