naming

ions

cations

• fixed charge metals: element name + ion (e.g. $\mathrm{Na}{}^{+}$, sodium ion)
• variable charge metals:
  • “modern naming”: Roman numerals (e.g. $\mathrm{Fe}{}^{3+}$, iron(III) ion)
  • “old naming”:
    • -ous for lower and -ic for higher oxidation state, e.g. ferrous and ferric for iron(II) and iron(III))

anions

• monatomic ions: ide suffix + “ion”
  • (e.g. $\mathrm{Cl}{}^{-}$: chloride ion, $\mathrm{O}{}^{2-}$: oxide ion)
• polyatomic ions:
  • see https://en.wikipedia.org/wiki/Polyatomic_ion#Nomenclature_of_polyatomic_anions)

ionic compound

$\text{cation anion}$

• cation (metal) first (as in cations, but without “ion” ending)
• anion (non-metal) second

molecular compound

• first: prefix-element (if > 1)
• second: prefix and ide suffix
