Basically, when you have an anion that is a combination of a non-metal with oxygen. According to my book: It ends with -ate for the most common oxyanions of the element. In other words, what does it even mean by "most common"?

Explanation: In naming ionic compounds , the name of the metal cation positively charged usually goes first followed by the name of the nonmetal anion negatively charged. The suffix -ide is only used if the nonmetal anion is monoatomic meaning one atom. Related questions How do you draw the lewis structure for polyatomic ions?

The number of protons are not suppose to be equal to the number of electrons? How come we are How do you calculate the total number of protons and electrons in a polyatomic Ion. Some compounds have been known for so long that a systematic nomenclature cannot compete with well-established common names.

The names of ionic compounds are written by listing the name of the positive ion followed by the name of the negative ion. We therefore need a series of rules that allow us to unambiguously name positive and negative ions before we can name the salts these ions form.

Some metals form positive ions in more than one oxidation state. One of the earliest methods of distinguishing between these ions used the suffixes -ous and -ic added to the Latin name of the element to represent the lower and higher oxidation states, respectively.

Chemists now use a simpler method, in which the charge on the ion is indicated by a Roman numeral in parentheses immediately after the name of the element. Negative ions that consist of a single atom are named by adding the suffix -ide to the stem of the name of the element.

It is still common to see and use the older naming convention in which the prefix bi- is used to indicate the addition of a single hydrogen ion. In general, when the binary acid is not in solution the name is as follows: 'Hydrogen' followed by the anion name ending in '-ide'. When the binary acid is in solution aq the name is as follows: 'Hydro-' followed by the anion name ending in '-ic' then add the word 'acid' to the end.
