If K and L shells of an atom are full then what would be the total number of electrons in the atom?

Number of electrons in nth shell= 2n2
Here n is the number of shell.
As K and L shell is completely filled hence, there would be (2+8) = 10 electrons in atom.
The element with atomic number 10 is inert gas neon (Ne) so the valency will be zero.
