Question

Write down the postulates of Bohr's Atomic Model

Guys please help me.. ​

Answer 1

Answer:

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 E

2

to a state of lower energy E

1

and in doing so, it emits a single photon of frequency,

v=

h

E

2

−E

1

where h is the plank constant.

Conversely, on absorbing an energy, E

2

−E

1

when the electron is at energy E

1

, the electron can take transition from E

1

to E

2

.

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

2π

h

.

thus L=

2π

nh

where n=1,2,3...

If radius of first bohr orbit is r

1

and radius of n

th

bohr orbit is r

n

then relation between them is given by,

r

n

=n

2

r
