For example, the conjugate base of sulfuric acid (H2SO4) is the polyatomic hydrogen sulfate anion (HSO−4). Polyatomic ions with a positive 1 charge do occur, but the main one you'll encounter and need to know is the ammonium ion. Plusieurs des ions polyatomiques fréquemment chargés négativement sont des oxydes d’éléments non-métalliques, et peuvent être considérés comme les bases conjuguées des acides correspondants. The vast majority of polyatomic ions are anions, many of which end in –ate or –ite.Notice that in some cases such as nitrate (NO 3-) and nitrite (NO 2-), there are multiple anions that consist of the same two elements.In these cases, the difference between the ions is in the number of oxygen atoms present, while the overall charge is the same. Changing the -ate suffix to -ite will reduce the oxygens by one, and keeping the suffix -ite and adding the prefix hypo- reduces the number of oxygens by one more. 20 of the most common polyatomic ions.

Start studying Polyatomic Ions (CHARGES). The naming pattern follows within many different oxyanion series based on a standard root for that particular series. The chlorite ion, ClO2–, contains 19 (7 from the Cl and 6 from each of the two O atoms) +1 = 20 electrons. (The prefix poly- carries the meaning "many" in Greek, but even ions of two atoms are commonly described as polyatomic. Unlike a molecule, which has a net charge of zero, this chemical species is an ion. If the total of the group numbers of the atoms is odd, it will need an odd number of electrons to make the total even. A polyatomic ion is a molecule that bears ionic groups, that is, a molecule with a charge.
