“Latin Method” Latin name of metal + “-ic” (For higher valence) / “-ous” (For lower valence) + Nonmetal + “-ide”
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"
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.
