Describe Neils Bohr’s atomic model.

Neils Bohr’s atomic model:

i. Electrons revolve around the nucleus in certain circular orbits (shells)

ii. The first shell nearest to the nucleus is called “K shell”. The subsequent shells as we move away from the nucleus are L, M, N,O respectively.

iii. The energy of an electron remains same as long as it revolves around its own shell.

iv. The shells also represent energy levels.

v. He proposed that each shell can accommodate a maximum of 2n² electrons (n= shell number)
