A polyatomic ion is an ion containing two or more atoms, usually of more than one element. An example is the nitrate ion. (NO−3 - ) This is 1 nitrogen with 3 oxygen's attached and bears a charge of 1-. The most common polyatomic ions are anions that contain oxygen attached to some other element called an oxoanion and are typically combinations of oxygen with a nonmetal. For a given nonmetal, there are often two or more common oxoanions SO32-(sulfite ion) 1 sulfur 3 oxygens and a charge of 2-,
The oxoanion that comes from nitric acid is nitrate (NO3-).
The term for a polyatomic anion containing one or more elements combined with oxygen is called an oxoanion. Oxoanions are formed when an element is bonded with one or more oxygen atoms to create a charged particle with an overall negative charge.
The oxoanion TeO4 2- is likely named tellurate, while TeO3 2- is likely named tellurite. They are analogous to the sulfur oxoanions sulfate (SO4 2-) and sulfite (SO3 2-), which are also from Group 6A.
Bleach (ilove2dance)Hydrochlorous acid does not exist. The -ous naming suffix is only used for anions that end in -ite, like the hypochlorite ion. However, an acid with that ion would be named hypochlorous acid. Hydro is only used as a prefix if the anion is not an oxoanion, one that contains oxygen. Hydrochlorous acid does not exist.
The name of an oxoanion ends with 'ate' when the central atom of it has the highest possible oxidation number. If it is slightly lesser (mostly 2), the common names of these compounds end with 'ite'. If the anion has no oxygen in it, usually it ends with 'ide'.
