Niels Bohr's model of an atom

The main points of the bohr's model of an atom was that due to the failure of the classical theories of physics as in the blackbody radiationa nd photoelectric effect among others had led him to assume that the energy is discrete, which was also verified by the planck's idea of quantization and therefore he took an arbitrary value that is h/2π as an basr value of the angular momentum of the orbit of an atom onto which the electron is supposed to revolve and that's why he put forth the relation L= nh/2π where L is the angular momentum and n is an positive integer and h is the plack's constant equal to 6.626*10^-34 which is also the lowest valued (mathematically) constant in physics .

Thomson's model of an atom

ANURAG SAMBHRIYA MODELS OF ATOM Thomson's model of an atom Thomson was a greater mentor and taught upto 7 person who have got noble prize incorporating rutherford who had disproven his model. His model is also called the plum pudding and watetmelon model of an atom as he had proposed that atlm is some sort of spherical ball onto which most of the posit ive charge is spread uniformly (just like the milk in the plum pudding and fleshy part in the watermelon)and negative charged electrons are embedded over it (just like the currents in the puddung and seeds in the watermelon )
