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
