Question

In an atom the number of electrons in M-shell is equal to the number of electrons in the K and L shell.
which is the outermost shell?electrons in outermost shell?atomic number of that element?electronic configuration?​

Answer 1

Answer:

M shell is the outermost shell which is also called a valence cell

when the atomic number is given then only electronic configuration is given otherwise we cannot guess them

Explanation:

M shell has 2 electrons maximum but L shell and M shell has eight shells maximum so KLM shell electrons cannot be equal at all
