2 Types of Ions Monatomic = 1 atom Names Representative elements TYPICALLY have only one possible chargeNamesCations = name of the elementCa2+ = Calcium ionAnions = remove ending, add “–ide”N3- = Nitride
3 These Transition Metals only have ONE charge!!! Types of IonsTransition metals and some representative elements have more than one charge.There are two ways to name these elements…Fe2+, Fe3+Cu+, Cu2+Sn2+, Sn4+Pb2+, Pb4+These Transition Metals only have ONE charge!!!Ag+Zn2+
4 Types of Ions Stock System Latin System Element name with charge in parentheses (Roman Numerals)Copper (I) = Cu+Latin SystemLatin root + suffix- ous = Lower charge- ic = Higher chargeFerric and Ferrous
5 Types of Ions Polyatomic Ions = A charged GROUP of bonded atoms Acts as ONE UNIT in an ionic bondCations: Only NH4+Anions: More common as polyatomicsLook at the back of the periodic table!!
6 Naming Ionic Compounds Cation is always named first (No # prefixes)Cation take the name of the elementTransition metals use the anion to find the charge of the cation(Roman numeral = charge)AnionMonatomic end in –idePolyatomic name from chart
