It is NH4+ and is called the ammonium ion. Prefixes Used to Indicate Number in a Name Involving Two Non-Metals mono– 1 hexa– 6 di– 2 hepta– 7 tri– 3 octa– 8 tetra– 4 nona– 9 penta– 5 deca– 10 These prefixes are used in naming binary compounds involving two non–metals. Example include P2O5, Cl2O, NO, N2O, NO2, N2O5, PCl3, PCl5, SO2, SO3, SiO2. Sometimes metal ions are involved in a Greek prefix name, but these are less common. Examples include UF6, SbCl3, SbCl5, OsO4, BiCl3. There is a preferred order of the nonmetals when writing them in a formula. It is: Rn, Xe, Kr, B, Si, C, Sb, As, P, N, H, Te, Se, S, I, Br, Cl, O, F. CO is carbon monoxide, NOT carbon monooxide. As4O6 is tetrarsenic hexoxide, NOT tetraarsenic hexaoxide. Acid Names – add the word acid to each name when saying or writing. Non–oxygen containing Oxygen containing (oxyacids) Name when dis- Name when a pure Formula solved in water compound Formula Name HF hydrofluoric acid hydrogen fluoride HNO3 nitric acid HCl hydrochloric acid hydrogen chloride HNO2 nitrous acid HBr hydrobromic acid hydrogen bromide H2SO4 sulfuric acid HI hydroiodic acid hydrogen iodide H2SO3 sulfurous acid HCN hydrocyanic acid hydrogen cyanide H3PO4 phosphoric acid H2S hydrosulfuic acid hydrogen sulfide H2CO3 carbonic acid HC2H3O2 acetic acid (Note that it is hydrogen sulfide, NOT hydrogen sulfuride.) (also written CH3COOH)
