What are the rules for naming polyatomic ions?
Rule 1. The cation is written first in the name; the anion (takes electrons) is written second in the name. Rule 2. When the formula unit contains two or more of the same polyatomic ion, that ion is written in parentheses with the subscript written outside the parentheses.
