Question

Write down the structure of atom given by neil bohr

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−E1/h

where h is the Planck's constant.

Conversely, on absorbing an energy,

E2−E1

when 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

h/2π

Thus, L=nh/2π

where n=0,1,2,...
