Part A: Naming ionic compounds that contain polyatomic ions Formula Name Table 1: NaBrO4 sodium perbromate Na2SO4 sodium sulfate Na3PO4 sodium phosphate 1. Explain why the different compounds in Table 1 above have different numbers of Na atoms in their formulas. Your answer should discuss the charges on the various polyatomic ions in the three ...
The rule for constructing formulas for ionic compounds containing polyatomic ions is the same as for formulas containing monatomic (single-atom) ions: the positive and negative charges must balance. If more than one of a particular polyatomic ion is needed to balance the charge, the entire formula for the polyatomic ion must be enclosed in parentheses, and the numerical subscript is placed outside the parentheses. Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO 3-, contains one nitrogen atom and three oxygen atoms.The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.

Write "hydroxide" for the ion OH- and "cyanide" for the ion CN-. Many, but not all, polyatomic ions follow these naming conventions. Refer to a chemistry textbook if you are unsure. In particular, organic ion names follow the same naming system as other organic compounds.

The formula for the compound will contain both a cation and an anion to balance the overall charge of the compound. The cation is named normally and the anion is given the name of the actual anion. An easy way to recognize these formulas is the fact that they are made up of more that two elements and, usually, the first element is a metal.
Writing formulas containing polyatomic ions: Use the cross-over method Simplify subscripts where possible, but never change the formula of a polyatomic ion ***peroxide cannot be simplified
