  1. Positively charged ions are called cations (named first) • Negatively charged ions are called anions • Cations can be metals or polyatomic ions • For metals that have only one possible charge (valency) the name of the metal is used.Examples are Group I metals (charge 1+), Group II metals (charge 2+), Aluminium (charge 3+), Zinc (charge 2+), Silver (charge 1+) • For metals that can have more than one charge (valency) the name of the metal is succeeded by the valency in capital Roman numerals in bracketsORby using the suffix -ous for the lowest valency and -ic for the highest valency and sometimes with the Latin name for the metal

  2. Anions can be a negatively charged element or a polyatomic ion • Negatively charged elements have the suffix -ideExamples are oxide (O2-), sulfide (S2-), fluoride (F-), chloride (Cl-), bromide (Br-), iodide (I-), nitride (N3-), hydride (H-) • Polyatomic ions which include oxygen in the anion have the suffixes -ate or -ite. "ate" means there is more oxygen in the anion than one ending in "ite"Examples: sulfate (SO42-) has more oxygen than sulfite (SO32-), nitrate (NO3-) has more oxygen in the anion than nitrite (NO2-)Other examples are carbonate (CO32-), phosphate (PO43-) and permanganate (MnO4-)Exception: OH- is named hydroxide

  3. MgO CATION: Mg2+ is named magnesium as magnesium belongs to Group (II) and can only have one charge (valency)ANION: O2- is named oxideName of compound is magnesium oxide

  4. FeS CATION: Fe2+ is named iron (II) or ferrous as iron can have a charge of either 2+ or 3+ANION: S2- is named as sulfideName of compound is iron (II) sulfide or ferrous sulfide

  5. LiH CATION: Li+ is named as lithium since lithium is a Group I metal and can have only one charge (valency)ANION: H- is named as hydrideName of compund is lithium hydride

  6. CaCO3 CATION: Ca2+ is named as calcium (since it is a Group II metal) and can only have 1 chargeANION: CO32- is named as carbonateName of compound is calcium carbonate

  7. FeSO4 CATION: Fe2+ named as iron (II) or ferrousANION: SO42- named as sulfate

  8. FeSO3 CATION: Fe2+ named as iron (II) or ferrousANION: SO32- named as sulfiteName of compound is iron (II) sulfite or ferrous sulfite
