The -ite or -ate ending in a polyatomic ion is simply an indication of the amount of oxygen atoms present. The -are ending is used in the base form. If the polyatomic ion has one less oxygen atom than the -ate form, the -ite form applies.

The -ite or -ate ending in a polyatomic ion is simply an indication of the amount of oxygen atoms present. The -are ending is used in the base form. If the polyatomic ion has one less oxygen atom than the -ate form, the -ite form applies.
The usual endings for polyatomic ions are "-ate" and "-ite." The "-ate" ending signifies the ion with the larger number of oxygen atoms, while the "-ite" ending signifies the ion with one less oxygen atom.
For polyatomic anions containing oxygen, or oxyions, the most common for of the ion has a name ending in -ate.
The suffix "-ite" indicates that the polyatomic ion has one less oxygen atom than the "-ate" ion with the same root name. For example, sulfate (SO4^2-) has one less oxygen atom than sulfite (SO3^2-). This naming convention helps differentiate between different forms of the same polyatomic ion.
The ide ending in a polyatomic ion actually has no practical meaning involved. The polyatomic compounds that do contain the ide ending have it because they were thought to be monatomic at one time.
The "ate" in carbonate refers to the oxygen atom and the negative charge it carries, denoting the presence of a polyatomic ion (CO3 2-). The "ate" ending is a common suffix used to indicate this type of ion in chemical nomenclature.
-ate has more oxygen than -ite.The full range of this naming strategy is illustrated by chloroxy ions:hypochlorite: ClO-chlorite: ClO2-chlorate: ClO3-perchlorate: ClO4-
Polyatomic ions with the suffix -ate typically contain one or more oxygen atoms. These ions often form from the combination of a central atom with oxygen and other elements, creating a negatively charged ion with a specific overall charge.

Respectively the higher and the lower state of oxidation of a nonmetal acid-forming oxide.Example:sulfite SO32- from SO2 from S in oxid.state +4forming sulfurous acid H2SO3sulfate SO42- from SO3 from S in oxid.state +6forming sulfuric acid H2SO4The -ate and -ite represent different polyatomic ions containing oxygen; the exact formula and number of oxygen atoms depends on the specific ion. An -ate ion typically has one oxygen atom more than an -ite ion.The -ate and -ite represent different polyatomic ions containing oxygen, the exact formula and number of oxygen atoms depends on the specific ion. An -ate ion typically has one oxygen atom more than an -ite compound. Compounds ending in -ate or -ite are typically salts.
The polyatomic ion is the ammonium ion, NH4^+
