K, L, M and N are energy bands that define their relationship with the nucleus. These electron shells were named by Charles G. Barkla.
He proposed that electron shells when hit by atoms produce different levels of X-rays or energy.
To make his study easy and simple, he divided the electron shells into K, L, M, N and marked them according to the x-rays they produced or emitted.
