For monatomic metal cations with a fixed charge, the name is simply the element name followed by the word "ion". - $\text{K}^+$: Potassium ion - $\text{Mg}^{2+}$: Magnesium ion - $\text{Ag}^+$: Silver ion ## Identify monatomic anions Anions are negatively charged ions. For monatomic anions, the suffix of the element name is replaced with "-ide", followed by the word "ion". - $\text{F}^-$: Fluoride ion - $\text{S}^{2-}$: Sulfide ion - $\text{P}^{3-}$: Phosphide ion ## Identify transition metals with variable charges Transition metals like copper can form ions with different charges. In systematic IUPAC nomenclature, Roman numerals in parentheses indicate the charge. - $\text{Cu}^+$: Copper(I) ion - $\text{Cu}^{2+}$: Copper(II) ion ## Identify polyatomic ions Polyatomic ions are groups of covalently bonded atoms with an overall charge.
