W12P1 (Per5): Ionic Compounds with Polyatomic Ions

Master naming ionic compounds with polyatomic ions and writing their formulas!

Match the name to the chemical formula CaBr2 calcium bromide Cr3N2 chromium (II) nitride Ca(BrO3)2 calcium bromate Cr(NO2)2 chromium (II) nitrite Cr(NO2)3 chromium (III) nitrite CrN chromium (III) nitride Elements in Group 1 (alkali metals) and Group 2 (alkaline earth metals) do not need Roman Numerals indicating their positive charge in ionic compounds, unlike transition elements. This is because metals in Groups 3-12 typically form more than one positive ion, so their charge in ionic compounds must be specified. For example, TiO2 is named titanium (IV) oxide. MgSO3 goes by the name magnesium sulfate magnesium sulfide magnesium sulfite Carl potassium phosphate has the chemical formula K3PO4 KPO4 K3P K2(PO4)2 FeBr3 is also known as... iron bromate iron (III) bromite iron (III) bromate iron (III) bromide What is the product of the following reaction in which metal ions combine with polyatomic anions? Remember: The charge of the product must balance to zero, so subscripts may be needed!Ba2+ + ClO- ---> ? BaClO Ba(ClO)2 Ba2ClO Ba2(ClO)2 What is the product of the following reaction in which metal ions combine with polyatomic anions? Remember: The charge of the product must balance to zero, so subscripts may be needed!Pb4+ + SO42- → ? Pb(SO4)2 PbSO4 PbS Pb2SO4 What is the product of the following reaction in which metal ions combine with polyatomic anions? Remember: The charge of the product must balance to zero, so subscripts may be needed!Na+ + SO32- → ? NaSO3 Na(SO3)2 Na2SO3 Na2S What is the charge of the tin (Sn) atom in SnO2? 1+ 2+ 3+ 4+ What is the charge of the Sn atom in SnSO3? 1+ 2+ 3+ 4+
