When a hydrogen atom forms compounds with the nonmetals, the hydrogen atom is named first and the nonmetal is named as if it were a negative ion. HF (g) hydrogen fluoride. ..The (g) for (gas state) must be shown since HF in a solution of water is called hydrofluoric acid. This is also done with HCl, HBr and HI. They are all in the same family. H 2 S (g) hydrogen sulfide. ..In a water solution this would be called hydrosulfuric acid. The following compounds are exceptions to this rule. .. H 2 O water. ..It is not known as dihydrogen oxide.

When other elements combine to form binary compounds, the formula is usually written by putting the elements in order of increasing group number. The number of atoms is given by a prefix , such as "mono", "di", "tri", "tetra", "penta", "hexa", "hepta" and "octa". ..for 1, 2, 3, 4, 5, 6, 7 and 8. Always use the entire prefix except for mon o oxide. ..which is named monoxide....
