Nomenclature

Chemical Names

• Start with the cation name, followed by the anion name; use prefixes to clarify any ambiguity
• Anion and cation names are derived from element names
• Organic compounds: Names are based on a separate nomenclature system; many compounds have common nonsystematic names

Chemical Formulas

• Cation symbol followed by anion
• Subscripts denote relative composition
• Enclose polyatomic ions or molecules in parentheses
• Molecular formula: Discrete molecule
• Empirical formula: Relative molar ratio of elements for solids or molecules

ferric, Fe (III)	ferrous, Fe (II)
stannic, Sn (IV)	stannous, Sn (II)
plumbic, Pb (IV)	plumbous, Pb (II)
cupric, Cu (II)	cuprous, Cu (I)
mercuric, Hg (II)	mercurous, Hg (I)

Metal Cations

• Alkali metal (+1); alkaline earth (+2)
• Transition metal: Valence varies; give the valence in the name and formula; -ous or -ic ending; roman numerals are less confusing, more general
