Bohr's second postulate

WebPlease wait... ... ... WebBohr’s second postulate: The radius of the orbit of an electron can only take certain fixed values such that the angular momentum of the electron in these orbits is an integral multiple of `h/(2π)`, h being Planck’s constant. Mathematical form: m e r n v n = `"nh"/(2pi)`

How was Bohr

WebAccording to Bohr’s Atomic model, the number of electrons that an orbit or shell can hold can be calculated using the formula: 2n2. Note- ‘n’ is the number of the orbit or shell. For K-shell n=1, for L-shell n=2, for M-shell n=3, and so on. The K-shell can hold a maximum of 2 electrons, the L-shell can hold a maximum of 8 electrons, and ... WebThis model was based on quantum theory of radiation and Classical law of physics.
