no it only has 1 valence electron so it's unstable.
yes
stable and chemically nonreactive, or inert.
Covalent bonds are the most stable because they share electrons to fill their outer shell- their valence shell- which make them completely stable. Unstable molecules are those that do not have a full outer shell, thus want to pair up and fill it.
For an element to be stable, it must have a full outer shell (valence shell) of electrons. An element with a full outer shell of electrons will act like its nearest noble gas and be stable. Most elements require 8 valence electrons to be stable, however H needs 2.
It has a full outer shell of electrons
Yes
No. It has one electron which is readily lost to produce the Na+ ion. Note - the ONLY elements with a complete outer shell are the noble gasses.
yes
The stable configuration is when an atom has a full outer shell.
an element is stable when it has a full outer shell of electrons. to abide by the octet rule it must have a shell of 2 then 8 electrons. An element with a full outer shell (8) will be stable and act like its nearest noble gas.

Sodium has ONE valence electron in its outer shell that is to be donated to any kind of oxidant. By then the outer (3rd) shell (of the Na+ ion) is EMPTY, so the 2nd shell has become the outmost, containing 8 electrons (Ne-configuration). No electrons at all are taken up by sodium.

The valence/outer shell has to be completely full to be completely stable.
Its outer shell is filled with electrons.
