why the shells have been named as K,L,M,N instead of A,B,C,D?

Expert Answer:

Barkla labelled them with the letters K, L, M, N, O, P, and Q. The origin of this terminology was alphabetic,though later experiments indicated that the K absorption lines are produced by the innermost electrons, this is the reason why k,l,m names are given to shells.
