Question

bohr's atomic model postulates

Answer 1

The Bohr's postulates -

1) An electron can revolve around the nucleus in certain fixed orbits of definite energy without emission of any radiant energy. Such orbits are called stationary orbits.

2) An electron can make a transition from a stationary state of higher energy E2 to a state of lower energy E1 and in doing so, it emits a single photon of frequency,

ν=E2−E1h where h is the Planck's constant.

Conversely, on absorbing an energy, E2−E1when the electron is at energy E1, the electron can make a transition from E1 to E2.

3) Only those orbits are allowed for which the angular momentum of the electron is an integral multiple of h2π,

Thus, L=nh2π where n=0,1,2,

Answer 2

Answer:

$\huge\bold\green{ANSWER:-}$

The Bohr model postulates that electrons orbit the nucleus at fixed energy levels. Orbits further from the nucleus exist at higher energy levels. When electrons return to a lower energy level, they emit energy in the form of light.
