Polyatomic ions & Common polyatomic ions (article) | Khan Academy
Polyatomic 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 Na + , Fe 3 + , Cl − , and many, many others.

Monatomic ion
If, instead of being monatomic, an ion contains more than one atom, even if these are of the same element, it is called a polyatomic ion. For example, calcium carbonate consists of the monatomic cation Ca2+ and the polyatomic anion ; both pentazenium () and azide () are polyatomic as well

IUPAC nomenclature of inorganic chemistry
Therefore, the name of the metal or positive polyatomic ion is followed by the name of the non-metal or negative polyatomic ion. See polyatomic ion for a list of possible ions.

多原子离子
在许多化学反应里,有一些物质,比如Ca(OH)2、CaCO3、H2SO4等,它们当中有一些“原子集团”:比如OH-、CO32-、SO42-等,常常作为一个整体参加反应,这样的原子集团称为 多原子离子(polyatomic ion)或 分子离子(molecular ion);旧的文献常不精确地称 原子团
