2. Naming Inorganic Compounds Positive ions (cations) Cations formed from metal atoms have the same name as the metal. Na + sodium ionZn 2+ zinc ion

3. Naming Inorganic Compounds Positive ions (cations) If the metal can form ions with more than one charge, the charge is in ( ). Co+ cobalt(  )Co2+ cobalt(  )

4. Naming Inorganic Compounds metal names Lower charge gets the ous Higher charge gets the ic Fe2+ = Fe(II) = FerrousFeCl 2 =ferrous chloride Fe3+ = Fe(III) = FerricFeCl 3 =ferric chloride Cu+ = Cu(I) = cuprousCuBr=cuprous bromide Cu2+ = Cu(II) = cupricCuBr 2 =cupric bromide Hg+ = Hg(I) = MercurousHgI= mercurous iodide Hg2+ = Hg(II) = MercuricHgI 2 =mercuric iodide

5. Naming Inorganic Compounds Positive ions (cations) Follow the poly atomic ion list for others

6. Naming Inorganic Compounds Negative ions (anions) Monotomic anions – drop the ending of the name and add –ide. H- hydrideO2- oxideBr- bromide Follow the polyatomic ion list for others.

7. Naming Inorganic Compounds Ionic compounds Name the cation followed by the anion CaCl2 calcium chloride Al2O3 aluminum oxide

8. Naming Inorganic Compounds Binary molecular compounds (covalent compounds) The name of the element farthest to the left in the table is written first. If in the same group, the lower one is named first The second element is given the ide ending Greek prefixes are used to indicate the number of each atom.

9. Standard prefixes 1mono6hexa 2Di7hepta 3tri8octa 4tetra9nona 5penta10deca

10. Naming Inorganic Compounds Naming Acids If the acid has no oxygen then simply add hydro as prefix and ic acid as suffix

11. Naming Inorganic Compounds Naming Acids If the acid contains oxygen use ic acid if the anion ends in ate and use ous acid if the anion ends in ite.

12. Naming Inorganic Compounds Naming Acids If the acid contains oxygen If the acid has one less O than the ite ion then uses hypo….ous acid If it has one more O than the ate ion then use per….ic acid.
