The -ite ending in a polyatomic ion usually signifies a lower oxidation state of the element, while the -ate ending indicates a higher oxidation state. This naming convention helps identify the composition and charge of the ion.
Both mean that the polyatomic ion contains oxygen along with another less electronegative element. "-ate" means that the polyatomic ion contains the number of oxygen atoms that was considered "normal" for the other electronegative element sometime during the 19th century when the system was introduced. "ite" means one oxygen atom less than the "-ate for the same other less electronegative element than oxygen. "-ate" means four oxygen atoms per polyatomic ion for sulfate and phosphate but only three oxygen atoms per polyatomic ion for chlorate and the other halates. One oxygen atom more than the "-ate" ion adds a "per" prefix to the basic "-ate" name, and one oxygen atom less than in an '-ite" ion adds a "hypo" before the basic "-ite" name. Example for one element: ClO3-1 is chlorate; ClO4-1 is perchlorate;
ClO2-1 is chlorite; and ClO-1 is hypochlorite.
There are many other possible complications in naming polyatomic anions; don't assume this covers everything.

What is polytomic ion?
A Polyatomic ion is a covalently bonded group of atoms that has a positive or negative charge and acts as a unit
If the name of a poly atomic ion ends in 'ate' what letters will be the formed from it end?
It will end in -ic acid. For example perchlorate --> perchloric acid
What is the difference between ite ate and ide at the end of a ion?
-Ite at the end of an ion means that the compound has 2 oxygen and -ate means there is 3 oxygen.
How can you tell if potassium sulfur is sulfite or sulfate?
K2S is potassium sulfide K2SO3 is potassium sulfite K2SO4 is potassium sulfate. In an ionic compound, the endings -ite and -ate indicate a negative ion that contains oxygen, with -ate indication more oxygen than -ite. The ending -ide usually indicates an oxygen-free ion with the exception of oxide and its variants.
What is the suffix of the ion with more oxygen atoms?
The suffix for an ion with more oxygen atoms is "-ate." For example, the sulfate ion (SO4^2-) has more oxygen atoms than the sulfite ion (SO3^2-).
What does a ite or ate ending in a polyatomic ion mean?
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.
What is polytomic ion?
A Polyatomic ion is a covalently bonded group of atoms that has a positive or negative charge and acts as a unit
What are the usual ending for the names of polyatomic ion?
ite or ate
What does an -ite or -ate ending in a polyatomic ion mean?
The -ite ending typically indicates a lower oxidation state or fewer oxygen atoms in a polyatomic ion, while the -ate ending typically indicates a higher oxidation state or more oxygen atoms. For example, sulfate (SO4^2-) has a higher oxidation state and more oxygen atoms compared to sulfite (SO3^2-).
What is the charge on the polyatomic ion cyanide?
The charge on the polytomic ion cyanide is -1.
What does the suffix -ate mean in chem?
In chemistry, the suffix -ate typically indicates that the compound contains oxygen and another element. It is commonly used in the names of salts or esters.
What are the usual endings for the names of polyatomic ions?
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.
What does the ate stand for in the carbonate?
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.
What dose an ite or ate ending in a polyatomic ion mean?
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.
Is a hydroxide ion positive charge?
No, a hydroxide ion has a negative charge. It consists of one oxygen atom and one hydrogen atom and has a net charge of -1.
What elements make up lithium and nitrate?
Lithium is an element itself, it is simply Li. Nitrate is Nitrogen and Oxygen, the -ate ending denoting an oxide ion!
What does the ide ending in a polyatomic ion mean?
The "-ide" ending in a polyatomic ion typically indicates that the ion contains only two elements, one being a nonmetal. This helps to distinguish it from ions with similar formulas but different compositions.
