Oxoanions (also called oxyanions) contain one element in combination with oxygen. Many common polyatomic anions are oxoanions that end with the suffix -ate. If an element has two possible oxoanions, the one with the element at a lower oxidation state ends with -ite. This anion will also usually have less oxygen per atom. Additional oxoanions are named with the prefix hypo- if they have a lower oxidation number than the -ite form and the prefix per- if they have a higher oxidation number than the -ate form. 

You already know how to name monatomic ions. How do you name polyatomic ions Most polyatomic ions are oxyanions. An oxyanlon is a polyatomic ion composed of an element, usually a nonmetal, bonded to one or more oxygen atoms. Many oxyanions contain the same nonmetal and have the same charges but differ in the number of oxygen atoms. More than one oxyanion exists for some nonmetals, such as nitrogen and sulfur. These ions are easily named using the following conventions. 

Polyatomic ions are two or more atoms bonded together that act as a single unit with a net charge. Many polyatomic ions are oxyanions, containing an atom, usually a nonmetal, and oxygen atoms. 

Naming oxyacids Another set of rules is used to name an acid that contains an oxyanion. An oxyanion is a polyatomic ion that contains oxygen. Any acid that contains hydrogen and an oxyanion is referred to as an oxyacid. 

To name oxyacids, you must first be able to recognize them by tbe general formula HaXbOc, with X representing an element other than hydrogen or oxygen (Section 5.1). It will also be useful for you to know the names of the polyatomic oxyanions (Table... 

Note in Table 4.4 that several series of polyatomic anions exist that contain an atom of a given element and different numbers of oxygen atoms. These anions are called oxyanions. When there are two members in such a series, the name of the one with the smaller number of oxygen atoms ends in -ite, and the name of the one with the larger number ends in -ate. 

Make flashcards for the common polyatomic ions listed in Table 4.4. Write the name on one side and the formula (with charge) on the other side. 2. Group all of the oxyanions together, and arrange these according to suffix (-ate or -ite). Notice the patterns. ...

Consider the Lewis structure for the polyatomic oxyanion shown here, where X is an element fiom the third period (Na—Ar). By changing the overall charge, 11, from 1— to 2— to 3— we get three different polyatomic ions. For each of these ions (a) identify the central atom, X (b) determine the formal charge of the central atom, X (c) draw a Lewis structure that makes the formal charge on the central atom equal to zero.
