Answer 2

Ideas of Bohr model:

Electrons revolve around the nucleus of an atom in fixed paths called orbits or shells.

Electrons in each shells have a definite energy. Hence shells are also known as energy levels.

As long as an electron revolve in a particular orbit , it's energy remains constant.

The energy of the shells increases as the distance from the nucleus increases.

The shells around the nucleus can be numbered from near the nucleus as 1,2,3,4,5...or represented by letters K, L, M, N, O .....
