8. Reminder: Guide for Naming Polyatomic Ions
Identify the cation and anion in the compound
Name the cation, using a ROMAN NUMERAL, if needed.
Name the polyatomic ion WITHOUT making any changes to the name.
Write the name of the compound, cation first, anion last.

9. Example Problems Name the following compounds: Pb(SO4)2 Pb? SO42-
Lead (IV) Sulfate
(NH4)2O
NH O2-
NH4+
Ammonium Oxide

10. Whiteboard Practice Only write the problem given on your board.
You will lose privileges and points for not following instructions.

11. Whiteboard Practice Name each of the following compounds: A. Sn(NO3)2
B. Mg(ClO2)2
C. Fe2O3
D. CuNO2
E. Al2(CO3)3

12. Whiteboard Practice Name each of the following compounds:
A. Sn(NO3) Tin (II) Nitrate
B. Mg(ClO2) Magnesium Chlorite
C. Fe2O Iron (III) Oxide
D. CuNO Copper (I) Nitrite
E. Al2(CO3) Aluminum Carbonate

13. Writing Formulas with Polyatomic Ions
The formula of an ionic compound
containing a polyatomic ion must have a charge balance that equals zero (0).
Na+ and NO3− -> NaNO3 (net charge of zero)
with two or more polyatomic ions, the polyatomic ion MUST be in parentheses.
Mg2+ and NO3− ->
NO3-
Net charge of zero!!
Mg(NO3)2
