What is the bond that is formed when one atom gives up a valence electron to another atom in order to fill the outer most electron shell of the other atom?

An ionic form is created because valence electrons are transferred. A covalent bond is when valence electrons are shared.

What change in electron structure occures when a sodium atom becomes a sodium ion?

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.
