Unformatted text preview: Ions The periodic table tells you what ion will form! Left cations Right anions Naming simple cations and anions The monoatomic anions are named by adding the suffix -ide to the stem of the name of the nonmetallic elements Ex Chloride ion The monoatomic cations bear the same names of the elements with the addition of the word 'ion'. Ex sodium ion Naming Type II cations transition metals Type II cations: Some metals (especially the transition metals) can form more than one type of cation, such as Fe 2+ and Fe 3+ or Cu + and Cu 2+ . To distinguish between these ions indicated the charge of the ion with a Roman numeral in parentheses (called the Stock number) immediately following the ion's name. Ex - Fe 2+ iron(II) ion and Fe 3+ iron(III) ion Naming Type I ionic compounds: metal + non-metal Type I: consisting of a metal combined with a nonmetal (e.g. NaCl) These metals always make the same cation so there is no need to list a Roman numeral. To name an ionic compound, one should name the cation first, then,...
