Question

What are the postulates of Bohr model of atom? Why was this model proposed by Bohr?

Answer 1

Answer:The amin postulates of Bohr's atomic model:

(i)The electrons revolving around the nucleus are confined to certain fixed orbits called shells or energy levels,each of which is associated with a fixed amnt of energy.

(ii) While it is revolving around the nucleus in an orbit,an electron neither loses nor gains energy.

(iii)An electron revolving in a particular orbit,on gaining a certain amnt of energy,jumps to the next orbit and vice versa.Since each orbit is associated with a fixed amnt of energy,Bohr called it an energy level.

answer to the next question:

It was proposed in order to explain the causes of the stability of the atom in a different manner.
