• Charged atom that has lost or gained an electron

• There are two different types of ions

• These are atoms that give up electrons

• The elements that give up electrons are METALS

• When a metal gives up an electron, it becomes positive

• These are atoms that take in electrons

• The elements that take in electrons are NONMETALS

• When a nonmetal takes in an electron, it becomes negative

• Ions = charged atoms that lost or gained an electron

• Cations are atoms that lost an electron

• Cations can only be metals

• Anions are atoms that gained an electron

• Anions can only be nonmetals
