outermost
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.
Only 2 electrons can reside in the innermost 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.

It's valance shell does not contain an octet of eight valance electrons. That simple.
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.
