N shell
The innermost shell can accomade 2 electrons
The innermost shell of every atom except hydrogen consists of 2 electrons.
Innermost is surely 2, as with every atom apart from Hydrogen?
K shell.
A full octet, valance shell. A valance shell with eight electrons, such as the Nobel gases have, doe not need to donate or accept electrons into or out of the valance shell to be stable.
Only 2 electrons can reside in the innermost shell.

The innermost shell of an atom, also known as the K shell, can hold a maximum of 2 electrons. This is determined by the formula (2n^2), where (n) is the principal quantum number of the shell. For the K shell, (n = 1), so (2(1^2) = 2). Therefore, there are 2 places for electrons in the innermost shell.
2
It has 6 electrons in it's valance shell and needs 2 more electrons in it's valance shell to become stable. Some atoms, phosphorous for instance ( valance # 5 ), can reach deeper into their valance shell and make additional covalent bonds.
