Multivalent Metals (Page 146) Multivalent metals are metals with more than one ion charge. These elements can form different ions depending on the chemical reaction they undergo. Examples of multivalent metals Copper (I) Oxide (contains Cu1+) Copper (II) Oxide (contains Cu2+) Copyright © 2010 McGraw-Hill Ryerson Ltd.

Writing Formulas and Names with Multivalents (Page 147) Using the reverse of the cross-over method, the form of iron involved must be Fe2+or Iron (II) Copyright © 2010 McGraw-Hill Ryerson Ltd.

Ionic Compounds with Polyatomic Ions (Page 148) Polyatomic ions are ions composed of more than one atom. Ternary compounds are compounds composed of three different elements. Whenever a polyatomic ion is involved in a reaction, a ternary compound is formed. Polyatomic ions have distinct names, as noted in the table above. Copyright © 2010 McGraw-Hill Ryerson Ltd.
