There are 2 valence electrons in an atom of magnesium. There are 5 valence electrons that are in an atom of phosphorus. There are 4 valence electrons that are in a silicon atom.
The electrons farthest away from the nucleus are the valence electrons of an atom.
the electrons in the outermost shell of an atom are considered to be the valence electrons.
Valence electrons
An ionic form is created because valence electrons are transferred. A covalent bond is when valence electrons are shared.
At least one, and usually all, of the valence electrons of the metal atom is donated to the valence shell of the nonmetal atom.

Valence electrons are those in the outermost shell of the atom.
The valence electrons are either lost to another atom or the sodium atom gains valence electrons, it really depends on if what the sodium atom is bonding with has a lot or a little of valence electrons. The structure doesn't change though, just the number of valence electrons change. The nucleus is never changed when an ion is formed.
The Lewis structure of an atom gives a clear illustration of the valence electrons.

nitrogen has 5 valence electrons. carbon has 4 valence electrons.
