If I have multiple amounts of a polyatomic ion then __ 00-00 You multiple the poly ion by the number from the other element's charge 00000 You need to put the poly ion in parenthesis 0 00000

## Step1: In a chemical formula, when we have multiple amounts of a polyatomic ion, we need to represent this in a specific way. ## Step2: We use parentheses to group the polyatomic ion together. This is because a polyatomic ion is a group of atoms that act as a single ion. ## Step3: After placing the polyatomic ion in parentheses, we then place the number of polyatomic ions outside the parentheses. This number is represented as a subscript.### The formula for this is: \((\text{{Polyatomic Ion}})_n\), where is the number of polyatomic ions.
