Question

In electronic configuration why shell give name k, m

Answer 1

we know that in an atom there are many shells in a atoms to recognise these shells named as
k 2
l 8
m. 8
n. 18
and other is 32 no of ectrons


And please make a answer a brain list answer

Answer 2

Explanation:

The names of the electron shell were given by a spectroscopist named Charles G Barkla. He named the innermost shell has k shell because he noticed that the X-rays emitted two types of energies. These energies were named as type A is higher energy X-ray and type B that is lower energy X-ray. Later these energies were named with different alphabets. He noticed that K-type X-rays emitted the highest energy. Therefore, he named the innermost shell the K shell.
