Ionic Compound Nomenclature Challenge - Polyatomic Ion Quiz
Today's objective is to understand and practice naming ionic compounds, focusing on Type I and Type II ionic compounds. The agenda includes a Polyatomic Ion Quiz 3 and writing ionic formulas. The homework involves reviewing various ionic compounds and their nomenclatures. The content also covers three types of ionic compounds: Type 1 - Binary compounds, Type 2 - Binary compounds with variable charge cations, and Type 3 - Polyatomic ion compounds. You will work on naming and writing formulas for different compounds, focusing on metals, nonmetals, and transition metals.

Three types of ionic compounds Type 1 - Binary compound (contains only two elements) and cation charge is known because atom can form only one type of ion. Metal forms only one type of ion: Groups 1A, 2A, Al3+, Ga3+, Zn2+, Cd2+, and Ag+ Type 2 Binary compound with variable charge cations. Transition metals and representative metals. Type 3 Polyatomic ion compound contains three or more elements contained within one or two polyatomic ions.
Type 1 Ionic Compounds Formed by electron transfer from a metal to a nonmetal Metal forms only one type of ion: Groups 1A, 2A, Al3+, Ga3+, Zn2+, Cd2+, and Ag+ Name as metal nonmetalide Name sodium chloride calcium oxide lithium fluoride beryllium nitride Formula Formula KBr Al2O3 ZnI2 Ag2S Name
Type 2 Ionic compounds Transition Metals Most transition metals and group 13-16 metals form multiple ions. Cr, Fe and Co form 2+ and 3+ ions Cu forms 1+ and 2+ ions Sn, Pb form 2+ and 4+ ions Mercury (II) is Hg2+, while Mercury (I) is Hg22+ Named as metal (roman numeral for charge on metal) nonmetalide Name lead (II) oxide tin (IV) fluride copper (I) bromide iron (III) selenide Formula Formula CuO Au2S CoP Cr3N2 Name
Type 3 Ionic compounds polyatomic ions Formula will have more than two elements Often includes oxygen Often includes () around a polyatomic ion Name as cation anion Name sodium carbonate tin (II) cyanide ammonium nitrate barium sulfate Formula Formula CuOH Mg(ClO2)2 FePO4 LiN02 Name
