Ionic BondingIonic Bonding
Ionic bonds form between Ionic bonds form between metalsmetals and and non-non-metalsmetals
MetalMetal atoms atoms loselose electrons to form electrons to form positivepositive ionsions
Non-metalNon-metal atoms atoms gaingain electrons to form electrons to form negativenegative ions ions
The oppositely charged ions attract one The oppositely charged ions attract one anotheranother
