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 ...

WebIn practice, the term is usually used more specifically to indicate that non-carbon atoms have replaced carbon in the backbone of the molecular structure. Typical heteroatoms are nitrogen (N), oxygen (O), sulfur (S), phosphorus (P), chlorine (Cl), bromine (Br), and iodine (I), [2] [3] as well as the metals lithium (Li) and magnesium (Mg). Solid nitrogen is a number of solid forms of the element nitrogen, first observed in 1884.
