Metals with variable valences
“Latin Method” Latin name of metal + “-ic” (For higher valence) / “-ous” (For lower valence) + Nonmetal + “-ide”
“Hydro-” + Nonmetal + “-ic” + “acid”
There are only 10 existing non-metals that can be involved in binary acids when combined with hydrogen: chlorine, fluorine, bromine, iodine, and sulfur. it can also equal an "-ide"
Binary Covalent Compounds
Nonmetal + Nonmetal + "-ide".
Add the appropriate Latin prefix to each element name to denote the number of atoms of each element present in a molecule of the compound. This method is generally not used with ionic compounds(see below), . For example, K2O is usually not called dipotassium monoxide, it is simply potassium oxide. P4O6, however, would be tetraphosphorus hexoxide. Some elements beginning with vowels (Oxygen, for example) replace the vowel ending of its prefix; mono- + Oxide = Monoxide, O4 = Tetroxide, O5 = Pentoxide, and so on.
Binary Ionic Compounds
If the anion is more than one atom of the same substance, either "ite" or "ate" is added at the end instead of "ide". "ite" is used when the anion is, "ate" if the anion is 3 or higher. Ex.: CaCl2 are common however... one being Iron(III) Oxide=Fe2O3.
Template:Inorganic-compound-stub If the compound is aqueous (aq) and begins with "H" then it can be read as hydro + ____ + ic acid. Example H2S is hydrosulfuric acid
