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 Na + , Fe 3 + , Cl , and many, many others. This article assumes you have a knowledge of basic monatomic ions as well as the ...Thu, 02 Apr 2026 01:28:00 GMThttps://www.khanacademy.org/science/hs-chemistry/x2613d8165d88df5e:chemical-bonding/x2613d8165d88df5e:ionic-nomenclature/a/polyatomic-ions-articleKhan Academy Sign upThu, 02 Apr 2026 13:09:00 GMThttps://www.khanacademy.org/science/hs-chemistry/x2613d8165d88df5e:chemical-bonding/x2613d8165d88df5e:polyatomic-ions/a/polyatomic-ions-articleBonding with polyatomic ions Like monatomic ions, polyatomic ions participate in ionic bonds with other ions (but remember, the atoms within a polyatomic ion molecule are held together by covalent bonds, which we will cover in more detail in the next lesson).

Even though they are made of multiple atoms, they act as a single unit in chemical reactions. You will encounter polyatomic ions often in chemistry, especially when studying compounds and reactions in solutions.Tue, 31 Mar 2026 11:17:00 GMThttps://www.khanacademy.org/science/ncert-class-9-science/x7e8d66f732d28ce4:atoms-and-molecules/x7e8d66f732d28ce4:molecules-and-ions/v/common-polyatomic-ions-dubvLet's review the common polyatomic ions, and look at the common suffixes and prefixes to help remember the formulas.Mon, 30 Mar 2026 13:20:00 GMThttps://fr.khanacademy.org/science/hs-chemistry/x2613d8165d88df5e:chemical-bonding/x2613d8165d88df5e:ionic-nomenclature/a/polyatomic-ions-articleLiaison avec les ions polyatomiques Comme les ions monoatomiques, les ions polyatomiques participent à des liaisons ioniques avec d'autres ions (mais souvenez-vous, les atomes à l'intérieur d'un ion polyatomique sont maintenus ensemble par des liaisons covalentes, que nous détaillerons dans la prochaine leçon).Fri, 03 Apr 2026 01:27:00 GMT
