1 Warm up take out a blank sheet of paper and match the following terms… 1. Made of two nonmetals 1. Made of two nonmetals 2. Made of a metal and a nonmetal 2. Made of a metal and a nonmetal 3. Makes atoms stable or “happy” 3. Makes atoms stable or “happy” 4. Ions are formed 4. Ions are formed 5. Molecules are formed 5. Molecules are formed 6. Forms compounds with different properties than individual elements 6. Forms compounds with different properties than individual elements 7. Electrons are lost or gained 7. Electrons are lost or gained 8. Electrons are shared 8. Electrons are shared 9. Can form double and triple bonds 9. Can form double and triple bonds 10. Can not form double or triple bonds 10. Can not form double or triple bonds Ionic Ionic Covalent Covalent Both Both

2 Chapter 19 Foldable

3 4 Flaps on the front 1. Writing Formulas 2. Naming Ionic Compounds (metal/nonmetal) 3. Naming Covalent Compounds (2 nonmetals) 4. Naming Polyatomic Ions (more than 2 elements)

4 Writing Formulas On flap On flap 1. Determine the oxidation number for 2 elements 2. Write symbols with metal first 3. Write oxidation numbers as superscripts 4. Crisscross method: No signs (subscripts). Do not put one! 5. Reduce Inside (Examples) Inside (Examples) Ba +2 Cl -1 Ba +2 F-1 BaCl 2 BaF 2 Fe +2 O -2 Fe 2 O 2 FeO

5 Naming Ionic (on Flap) Write name of the 1 st atom (cation) Write name of the 1 st atom (cation) Write root name of 2 nd atom (anion) Write root name of 2 nd atom (anion) Add –ide to ending Add –ide to ending Transition elements have varied oxidation number (use chart) Transition elements have varied oxidation number (use chart) Use oxidation number of negative to figure out (crisscross backwards) Use oxidation number of negative to figure out (crisscross backwards) Use Roman Numeral Use Roman Numeral

6 Naming Ionic (inside) Examples Examples CaCl 2 : Calcium Chloride CaCl 2 : Calcium Chloride Li 2 S: Lithium Sulfide Li 2 S: Lithium Sulfide MgF 2 : Magnesium Floride MgF 2 : Magnesium Floride NaCl: Sodium Chloride NaCl: Sodium Chloride Copper (I): Cu + Chromium (II): Cr +2 Copper (I): Cu + Chromium (II): Cr +2 Copper (II): Cu +2 Chromium (III): Cr +3 Copper (II): Cu +2 Chromium (III): Cr +3 Iron (II): Fe +2 Lead (II): Pb +2 Iron (II): Fe +2 Lead (II): Pb +2 Iron(III): Fe +3 Lead (IV): Pb +4 Iron(III): Fe +3 Lead (IV): Pb +4 Zinc: Zn +2 Silver: Ag +1 Zinc: Zn +2 Silver: Ag +1 CuCl 2: Copper (II) Chloride CuCl 2: Copper (II) Chloride Cu +2 Cl -1 Cu +2 Cl -1 CrCl 3 Chromium (III) Chloride CrCl 3 Chromium (III) Chloride Cr +3 Cl -1 Cr +3 Cl -1

7 Naming Covalent (on Flap) From chart look at element and subscript From chart look at element and subscript Add the correct prefixes to the elements name Add the correct prefixes to the elements name 1: mono not needed on the first element 1: mono not needed on the first element Look at second element, add prefix to root word. Look at second element, add prefix to root word. 1: mono need 1: mono need Change ending to -ide Change ending to -ide

8 Covalent Prefixes (put inside) 1: mono- 1: mono- 2: di- 2: di- 3: tri- 3: tri- 4: tetra- 4: tetra- 5: penta- 5: penta- 6: hexa- 6: hexa- 7 hepta- 7 hepta- 8 octa- 8 octa-

9 Covalent examples (inside) NO NO Nitrogen Monoxide Nitrogen Monoxide N 2 O 5 N 2 O 5 Dinitrogen pentoxide Dinitrogen pentoxide CO 2 CO 2 Carbon Dioxide Carbon Dioxide H 2 O H 2 O Dihydrogen monoxide Dihydrogen monoxide

10 Naming Polyatomic (On flap) 1. Write name of cation 2. Use table to find the names of polyatomic

11 Polyatomic Inside Na + (NO 3 ) + Na + (NO 3 ) + Na(NO 3 ) Na(NO 3 ) Sodium Nitrate Sodium Nitrate
