1. Naming Polyatomic Compounds

2. OUTCOME QUESTION(S): C11-3-06 NAMING AND EQUATIONS
Write the formulas and/or names for any general ionic, covalent, or polyatomic compound.
Write and classify balanced chemical equations from written descriptions of reactions.
Classify the type of reaction and predict the products to create a complete balanced equation.
Vocabulary & Concepts 

3. OCl2 oxygen dichloride MgCl2 magnesium chloride CuCl2
Does it have a metal?
YES (ionic)
Is it a transition?
NO (covalent)
NO charges
NO criss-cross
Use prefixs
Ends in “ide” NO
YES
Find charges
Criss-cross
Ends in “ide”
Find charges
Reverse Criss-cross
Use Brackets
Ends in “ide”
OCl2
oxygen dichloride
MgCl2
magnesium chloride
CuCl2
copper (II) chloride

4. Al(C2H3O2)3 Polyatomic Ions (poly = many)
Groups of covalently bonded atoms that act as ions.
Polyatomic ions function as one unit with one ionic charge – gain or lose electrons.
Al(C2H3O2)3
Aluminum Acetate
Note the ending (not “ide”) – the ending is the clue that it is polyatomic and NOT a plain element

5. There are a few “ides” BUT they are obviously not elements

6. Mg NO3 Mg(NO3) magnesium nitrate Write the name of the ionic compound:+ 2 - 1
Mg NO3
Mg(NO3) 2 2
magnesium nitrate
We get the valences (charges) and criss-cross – just like building any ionic compound

7. OCl2 oxygen dichloride MgCl2 CuCl2 magnesium chloride
Does it have a metal?
YES (ionic)
Is it a transition?
Polyatomic
NO (covalent)
Find charges
Reverse Criss-cross
Don’t change ending
NO charges
NO criss-cross
Use prefixs
Ends in “ide”
Fe(NO3)2
iron (II) nitrate NO
Find charges
Criss-cross
Ends in “ide”
YES
Find charges
Reverse Criss-cross
Use Brackets
Ends in “ide”
OCl2
oxygen dichloride
MgCl2
magnesium chloride
CuCl2
copper (II) chloride
If you are having trouble naming, take a screen shot of this and save it somewhere to reference…

8. Ni(NO3)2
magnesium sulfate
KMnO4
iron (III) hydroxide
Ca(C2H3O2)2
silver chromate
PbCO3
tin (IV) sulfate
Na2HPO4
ammonium nitrite
nickel (II) nitrate
MgSO4
potassium permanganate
Fe(OH)3
calcium acetate
Ag2CrO4
lead (II) carbonate
Sn(SO4)2
sodium hydrogen phosphate
NH4NO2
