This convention should also be applied to all compounds and derivative names of these chemicals: Capitalization of elements and compounds[ edit ] In former versions of the IUPAC recommendations, names were written with a capital initial letter. This practice has been abandoned in later publications.
Phosphate ion PO Pattern 1: For instance, if you know nitrate is NO3-,then nitrite is NO If you know phosphate is PO,then you know phosphite is PO You can also use the prefixes hypo- and per- with the chlorate series. Hypochlorite is a double whammy: You can also substitute the other halogens for Cl and make additional sets of the series.
The -ates with charges less than negative 1 that is, ions with charges of -2, -3, etc. HCO3-is called either the bicarbonate ion or the hydrogen carbonate ion. These are named hydrogen phosphate and dihydrogen phosphate, respectively.
That means you need to see the naming acids rules. The following periodic table will also come in handy. Working backward from the halogens, or 7A family, the oxidation states are most commonly -1, while the 6A family is -2, and the 5A family is Naming acids is extremely easy if you know your polyatomic ions.
There are three rules to follow: HCl is hydrochloric acid; H2S is hydrosulfuric acid. When you see an acid name beginning with hydro- think: HCN is an exception since it is a polyatomic ion without oxygen, so it is named hydrocyanic acid.
If the acid has an -ate polyatomic ion after the H, that makes it an -ic acid. H2SO4 is sulfuric acid.

When the acid has an -ite polyatomic ion after the H, that makes it an -ous acid. H2SO3 is sulfurous acid.Chemical Foundations measurement, significant figures, precision & accuracy, conversion factors, matter: Atoms, Molecules and Ions atomic theory, intro to Periodic Table, formulas & .

From Wikipedia:Naming conventions. Generally, article naming should give priority to what the majority of English speakers would most easily recognize, with a reasonable minimum of ambiguity, while at the same time making linking to those articles easy and second nature.
