Question

if K and l shell of an atom are full then what would be the total number of electron in the atom

Answer 1

10 electrons are there in that atom because
k shell=2 e-
l shell = 8e-

Answer 2

Answer:

Neon

Explanation:

The maximum number of electrons that can occupy K and L shells of an atom are 2 and 8 respectively. Therefore, if K and L shells of an atom are full, then the total number of electrons in the atom would be (2 + 8) = 10 electrons.
