Unformatted text preview: Example: Potassium is a Group 1A metal. It forms the +1 potassium cation: K + Anion name = element name with the ending replaced by the suffix "ide" . Anion Charge = Group number - 8 Example: Sulfur is a Group 6A nonmetal. It forms the (6 - 8 = -2) sulfide anion: S 2-Compound name = cation name + anion name Compound Charge = 0 The number of cations and anions must balance so that the overall charge is zero. Example: Potassium sulfide = K 2 S Note that there must be 2 potassium 1+ cations because sulfide has a 2- charge. Note also that the name ends in ide . Binary compounds always end in 'ide'....
