none, it wants to give up one. chlorine by it self has a -1 negative charge, which means it has one extra electron. sodium (Na) has a +1 charge, which means it wants to gain one. Cl gives up its electron and Na takes it to form a strong ionic bond and the compound NaCl (table salt)
The outer shell is the valence electrons and they are very loosely bound to the nucleus - less force by the nucleus on the valence electrons, so valence shell's electrons are exchanged first in any reaction.

The Carbon has double bonds to each of the oxygen atoms, so it does not have any unshared pairs or electrons. Valence shell electron pair repulsion theory dictates that the electron pairs will be repel, so the farthest apart they can be is 180 degrees apart or linear.
In terms of struture, lone pairs contribute helping a molecule acquire a shape as dictated by VSEPR Theory (Valence Shell Electron Pair Repulsion Theory). Regarding chemical properties lone pair/s of electrons can make a molecule act as a Lewis base (like ammonia) in the reaction mixtures the extent of which depends on various other features in the structure of molecule.

The outer shell is called the valence shell
The valence shell is the outer most shell or imaginary orbit of an atom containing <8 electrons. The electrons in this shell are called 'valence electrons'.

the electrons in the outermost shell of an atom are considered to be the valence electrons.

11 electrons makes the third energy level complete. One
Valence Electrons
Chlorine needs one additional valence electron to have a full valence shell, as it has seven valence electrons in its outermost shell and aims to have a complete octet with eight electrons for stability.
No. Nitrogen has five electrons in its valence shell.
There are 6 valence electrons in the sulfur atom.
The VALENCE Shell. In any chemical reaction it is the electrons in the Valence Shell that do the reacting. Any inner shells of electrons do NOT take part in a chemical reaction.
