Naming Oxy-ions ‣ All 20 oxy-ions have the same charge as their central atom normally prefers — except carbon and nitrogen ‣ P and S oxy-ions have 3 or 4 oxygens. ‣ C,N,Cl,Br, and I oxy-ions have 2 or 3 oxygens. ‣ The “ite” ion is always the one with less oxygens. ‣ The “ate” ion is always the one with more oxygens.
The Common Polyatomic Ions Chart provides a list of common ions with their respective formulas. It is used to help identify and write the formulas for these ions in chemical compounds.
Ions. Made of a single atom: monatomic ion. Made of more than one atom: polyatomic ion. Named by: the name of the element ∙ the word ion or cation. Named by: the root of the name of the element ∙ -ide. EXTENSION Extend the concept map by providing an example of each of the four types of ions.
