Nomenclature Review
Date: __________
In the beginning was binary ionic nomenclature. . .
First were the representative metals bonded to an anion.
1. Where are the representative metals found? s and p blocks 2. What are anions? Negative ions
3. Have anions gained or lost electrons? Gained 4. Where are anions found on the period table? Right
When the cation Ca2+ bonds with the anion Cl1- the compound formed is CaCl2.
5. What is the 2 called in the formula? Subscript 6. What does it tell us about the compound? There are two
chlorine atoms.
Then came the transition metals and those metals under the step-ladder who required a special
Roman numeral after their names. 7. What does the Roman numeral tell us about the metal? The charge.
Utilize your nomenclature knowledge for the following binary ionic compounds:
Name these compounds:
8. CaO Calcium oxide
11. TiO2 Titanium (IV) oxide
9. CuO Copper (II) oxide
12. MgS Magnesium sulfide
10. Mn2O3 Manganese (III) oxide
13. PbCl2 Lead (II) chloride
Write the formulas for these:
14. Lithium sulfide Li2S
15. Mercury (I) oxide Hg2O
16. Tin (II) fluoride SnF2
17. Lead (IV) oxide PbO2
18. Barium nitride Ba3N2
19. Cesium bromide CsBr
Score: 19/19 – whoo!
Then came the polyatomic ions.
20. Given the example compound Cu(C2H3O2)2, what does the subscript 2 outside the parentheses tell us?
There are two acetate molecules.
21. What Roman numeral would follow copper in the name of the compound? II
Name these compounds:
22. KClO4 Potassium perchlorate
23. Fe(C2H3O2)2 Iron (II) acetate
24. Ba3(PO4)2 Barium phosphate
25. (NH4)2CO3 Ammonium carbonate
26. PbSO4 Lead (II) sulfate
27. Cr(OH)2 Chromium (II) hydroxide
Write the formulas for these:
28. Mercury (II) carbonate HgCO3
29. Sodium sulfite Na2SO3
30. Copper (II) phosphate Cu3(PO4)2
31. Vanadium (III) oxide V2O3
31. Calcium chlorite Ca(ClO2)2
32. Cobalt (III) sulfate Co2(SO4)3
33. Nickel (II) hydroxide Ni(OH)2
34. Lithium cyanide LiCN
Score: 16/16 – go me!
Next came the nomenclature of acids.
35. What element do all acids have? Hydrogen
36. All binary acids have the prefix Hydro-.
37. Acids with a polyatomic ion that ends in -ate change to the ending -ic.
38. Acids with a polyatomic ion that ends in -ite change to the ending -ous.

Nomenclature Review
Name these acids:
39. HClO3 Chloric acid
40. H2S Hydrosulfuric acid
Date: __________
41. HBr Hydrobromic acid
42. HNO2 Nitrous acid
Write the formulas:
43. Hydrochloric acid HCl
44. Phosphoric acid H3PO4
45. Acetic acid HC2H3O2
46. Hydroiodic acid HI
Score: 12/12 – I’m awesome.
Last in nomenclature came the naming of two or more nonmetals bonded together.
47. Nonmetals are located to the right on the period table. These compounds do not have ions (charges)
because the elements are not gaining or losing electrons. They are sharing their electrons.
48. Therefore, these compounds use prefixes such as mono, di, tri.
Name these compounds:
49. N2O5 Dinitrogen pentoxide
50. PCl5 Phosphorus pentachloride
51. NO Nitrogen monoxide
52. P4O10 Tetraphosphorus decoxide
Write the formulas:
53. Dinitrogen monoxide N2O
54. Carbon tetrabromide CBr4
55. Carbon monoxide CO
56. Nitrogen dioxide NO2
Score: 10/10 – mere bag o’ shells.
Challenge: All types are mixed. Name them and write the formulas.
