Well, a polyatomic may contain a cation in it. A cation is a positively charged ion. They are usually metals. A good way to remember is: "cats" have "paws" because they are "pawsitive". Cheesy, right? Anyways, an example of a polyatomic that contains a cation is NH4+. You know that this polyatomic has a cation by the +1 superscript. This + sign signifies a positive ion, which is called a cation!

How are polyatomic ions named in an ionic compound?
Polyatomic ions are named with their specific names, regardless of their overall charge. When naming an ionic compound with a polyatomic ion, the name of the cation is written first followed by the name of the anion (polyatomic ion).
Is potassium iodide a poly atomic ion?
No, potassium iodide is a compound composed of the monatomic ion K+ (potassium cation) and the monatomic ion I- (iodide anion). It is not a polyatomic ion.

How do you do the criss cross method when using a polyatomic ion?
When using the criss cross method with a polyatomic ion, simply treat the polyatomic ion as a single unit. Cross the charges of the cation and anion to determine the subscript of the other ion. Ensure to simplify the ratio by reducing to the lowest whole numbers.
Is Na2Cr2O7 ionic with a polyatomic ion?
