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.
valence electrons
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.
electrons
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 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'.

Valence Electrons
The valence electrons are involved in chemical bonding.
In the outermost shell that has electrons in it, those are called the valence electrons. For example carbon has 6 electrons, but only 4 are valence electrons because there are 2 in the shell in between it and the center of the element and 4 on the outside shell.
The electrons in the outermost shell is called as valence electron. These electrons are free and they are involved in bonding reactions.
Nitrogen has 5 valence electrons. Its atomic number is 7 therefore it has a total of 7 electrons. If you put this in a Bohr-Rutherford Diagram, there would be 2 electrons in the first shell (Helium structure) and 5 electrons in the outer shell. The number of electrons in an element's outermost shell is its number of valence electrons.
The name most often given to the outermost shell of electrons in the context of atomic structure is the valence shell.
The outer shell is called the valence shell
