STRUCTURE AND BONDING.

Ionic (Electrovalent) Bonding

Noble gases like neon or argon have eight electrons in their outer shells (or two in the case of helium).

These noble gas structures are thought of as being in some way a “desirable” thing for an atom to have.

When other atoms react, they try to organize electrons such that their outer shells are either completely full or completely empty.
