Ionic BondsIonic Bonds

Ionic Bonds-Ionic Bonds- the force of the force of attraction between the attraction between the opposite charges of ions.opposite charges of ions.

The giving and taking of The giving and taking of electrons (+ with -)electrons (+ with -)

IonsIons- Atoms that have a - Atoms that have a chargecharge
