WebThe oxidation state of an atom in any pure element, regardless of whether monatomic, diatomic, or polyatomic, is zero. A monatomic ion’s oxidation state is the same as its charge—for example, Na+ = +1, Cl = −1. Fluorine’s oxidation state in chemical compounds is always −1. Test your knowledge on How To Calculate Oxidation Number. WebPolyatomic ions. In this article, we will discuss polyatomic ions. The prefix poly- means many, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom. Examples of monatomic ions include \text {Na}^+ Na+, \text {Fe}^ {3+} Fe3+, \text {Cl}^- Cl−, and ...
