Strict nomenclature rules suggest mono should be applied to the second element in these compounds, but this is almost always dropped. Additionally these compounds can also be named as binary acids when they are in solution. This distinction is important in subsequent topics but less so here. 2. Although silver and zinc are d-block elements they do not commonly exhibit charges other than +1 and +2 respectively in compounds. As a result (I) and (II) are commonly omitted from nomenclature. 3. Here antimony is being treated as a metal hence the charge is stated, in other instances it may be treated as a non-metal. If so an alternative name here would be antimony trifluoride. 4. Here antimony is paired with the chlorate ion, so it is reasonable to assume it carries a charge too, hence the use of (V). See note 3. 5. Ds is the symbol for element 110, named in 2003. Here it is assumed it could take on a number of different charges in a compound, one of which is +3. C:\Adrian Dingles Tempopary Directory\rwsheet04fanswers.doc Page 4 of 4 .
