3 Objectives 1. To learn to name binary compounds of a metal and nonmetal 2. To learn to name binary compounds containing only nonmetals 3. To summarize the naming of all types of binary compounds 1. A x B y where A is a metal, B is a non-metal 2. C x D y where C and D are non-metals

4 A. Naming Compounds That Contain a Metal and a Nonmetal Binary ionic compounds contain positive cations and negative anions. Type I compounds Metal present forms only one cation Type II compounds Metal present can form 2 or more cations with different charges

5 A. Naming Compounds That Contain a Metal and a Nonmetal

6 A. Naming Compounds That Contain a Metal and a Nonmetal For compounds containing both a metal and a nonmetal, the metal is always named first. The nonmetal is named from the root element name.

7 A. Naming Compounds That Contain a Metal and a Nonmetal Type I Binary Ionic compounds Rules A Use your Machine to identify and name the following: NaCl, MgO, LiBr, CaF 2, Al 2 O 3

8 A. Naming Compounds That Contain a Metal and a Nonmetal Type II Binary Ionic compounds Since the metal ion can have more than one charge, a Roman numeral is used to specify the charge. Rules B Gold (I) Chloride Gold (III) Chloride

9 A. Naming Compounds That Contain a Metal and a Nonmetal Type II Binary Ionic compounds

10 What are the Formulas that would be formed from the following ions and what are the Names of the compounds? Cu + and F - Cu 2+ and F - Ni 3+ and I - Fe 2+ and O 2- Pd 4+ and Cl - Ti 4+ and P 3-

11 Name the following compounds: FeCl 2 CoS CoBr 3 PbI 2 CuO SnO 2 Fe 2 O 3

12 B. Naming Binary Compounds That Contain Only Nonmetals (and Metalloids) Type III Compounds Non-metal/Non-metal Rules C

13 B. Naming Binary Compounds That Contain Only Nonmetals (and Metalloids) Type III Compounds Name: N 2 O CO 2 PCl 5 SiO 2 NI 3 SeO B 2 O 3 XeF 4 SO 3 O 2 F 2

14 C. Naming Binary Compounds: A Review

15 Binary Compounds What are the names of these compounds? (Use your machine to identify the type first) CuO Ag 2 S SrO ClF B 2 O 3 Na 3 P TiCl 4 MnF 2 K 2 S NH 3 OF 2 CuCl 2

16 Binary Compounds Write the formula for the following compounds: Scandium oxide Xenon tetrafluoride Nickel (III) sulfide Dihydrogen monoxide Sodium oxide Copper (II) chloride

17 Objectives 1. To learn the names of common polyatomic ions 2. To learn to name compounds containing polyatomic ions 3. To learn how the anion composition determines an acid s name 4. To learn names for common acids 5. To learn to write the formula for a compound, given its name

18 A. Naming Compounds That Contain Polyatomic Ions Polyatomic ions are charged entities composed of several atoms bound together ( charged molecules ). Compounds should be electrically neutral Use parentheses (when appropriate) in writing formulas e.g Ni(CN) 2 They should be considered as other ions in determining names of compounds They have special names which should be memorized.

20 A. Naming Compounds That Contain Polyatomic Ions Naming ionic compounds containing polyatomic ions follows rules similar to those for binary compounds. ammonium acetate Rules D

21 Naming Compounds That Contain Polyatomic Ions Name the following compounds (are they Type I or II metals?): - NaOH - Na 2 CO 3 - CuOH - Cu(OH) 2 - Cu 2 SO 4 - Zn(NO 3 ) 2 - Fe 3 (PO 4 ) 2 - NaC 2 H 3 O 2 - (NH 4 ) 2 CO 3

22 Give formulas for the following compounds Sodium hydroxide Barium phosphate Magnesium acetate Copper (I) nitrate Iron (II) sulfate Cobalt (III) carbonate

23 B. Naming Acids An acid is a molecule with one or more H + ions attached to an anion. When dissolved in water the H + ion and anion separate. Rules E

24 B. Naming Acids

25 B. Naming Acids Rules F

26 B. Naming Acids Acids of Oxyanions

27 B. Naming Acids

28 Name, and give the formula for, the acids made from the following anions: - Chloride - Nitrate - Bromide - Cyanide - Acetate - Sulfite - Sulfate - Fluoride - Phosphate

29 Acids You Should Know Hydrochloric Acid (HCl) many industrial uses, stomach acid Sulfuric Acid (H 2 SO 4 ) major commercial chemical ~200 million Tons annually Nitric Acid (HNO 3 ) used to make fertilizers and explosives Acetic Acid (HC 2 H 3 O 2 ) vinegar Carbonic Acid (H 2 CO 3 ) ocean acidification, sodas Hydrofluoric Acid (HF) etches glass, very toxic
