  1. Names of Ionic Compounds

  2. Naming Ionic Compounds • When naming ionic compounds the following steps are followed: (1) Separate the compound into its positive and negative parts (Note that the positive part of a compound will be only the first element with the exception of ammonium which is NH4+) (2) Write the name of the cation followed by the name of the anion.

  3. Teacher Examples • Cr3(PO4)4 • Cr(CN)2 • Mg(CN)2

  4. Write the name of ZnO

  5. Zinc Oxide • Zinc oxide is added to many breakfast cereals, as a source of zinc; a necessary nutrient. • Because it absorbs both UVA and UVB rays of ultraviolet light, zinc oxide can be used in ointments, creams, and lotions to protect against sunburn and other damage to the skin caused by ultraviolet light.

  6. Write the name of CuO

  7. Copper (II) Oxide • Copper (II) oxide can be used in batteries. • Copper (II) oxide is used as a pigment in ceramics to produce blue, red, and green (and sometimes gray, pink, or black) glazes.

  8. Write the name of Fe2(SO4)3

  9. Iron (III) Sulfate • Medically it is used as an astringent (shrinks mucous membranes) and styptic (contracts blood vessels to stop bleeding).

  10. Write the name of MnCO3

  11. Manganese (II) Carbonate • Manganese (II) carbonate is widely used as an additive to plant fertilizers to cure manganese deficient crops. • It is also used in health foods (Manganese is an essential dietary mineral in very small quantities. A deficiency in manganese can cause skeletal deformations and inhibits the healing of wound healing.)

  12. Write the name of Ag2S

  13. Silver Sulfide • Silver sulfide is the tarnish that forms on silver when exposed to the atmosphere.

  14. Name the following compounds • SrCl2 (b) Cr(OH)2 (c) KClO4 (d) NH4MnO4 (e) NiP

  15. Name the following compounds • SrCl2strontium chloride (b) Cr(OH)2chromium(II) hydroxide (c) KClO4potassium perchlorate (d) NH4MnO4ammonium permanganate (e) NiP nickel(III) phosphide
