Q

what are the rules for naming Ionic compounds with polyatomic ions

A
  1. The cation is written first in the name; the anion is written second in the name.
  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.
  3. If the cation is a metal ion with a fixed charge, the name of the cation is the same as the (neutral) element from which it is derived
  4. If the anion is a monatomic ion, the anion is named by adding the suffix -ide to the root of the element name
