Ionic and Covalent Bonding

IONIC BONDING When an atom of a nonmetal takes one or more electrons from an atom of a metal so both atoms end up with eight valence electrons.

Ionic Bonding. What is Ionic Bonding? One type of bonding where valence electrons transfer from: METAL atom to a NONMETAL atom ◦ ONLY VALENCE ELECTRONS.

Ionic Bonding. CA Standards  Students know atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons.
