Answer:
Hence energy levels increase as the distance from the nucleus increases. There are many shells around the nucleus which are arced as K, L, M; N, and so on.
...
M SHELL.
Shells Electrons
K -2
L -8
M- 18
Total Electrons -28

Answer:
Explanation:
Neils Bohr gave the planetary model of an atom. He was the first person to suggest the periodicity in the properties of the elements. “Bohr atomic model” forms the basis of the electronic structure of an atom. He was the person to describe the arrangement of electrons (electronic configuration) in different orbits/shells.
He proposed that electrons are distributed in circular electronic shells (orbits). These electrons revolve in the orbits around the nucleus from a fixed distance. In this topic, we will learn more about the electronic configuration of different elements.
