Review of Naming Ionic Compounds

• Cation first in name and formula
• Monatomic anion name ends in ide
• Monatomic cation (metal) name remains same as
  its atom
• Give charge for transition metals (i.e. Fe, Cr,
  Mn)

Examples Manganese (III) oxide Potassium
dichromate Magnesium nitrate
Mn2O3 Mn3 O-2
K2Cr2O7 K1 Cr2O7-2
Mg(NO3)2 Mg2 NO3-1

Review of Naming Molecular Compounds

• First element listed in name or formula keeps its
  atomic name. Second element ends with ide.
• Must state the number of each element in the name
  using the Greek prefixes. (i.e. mono, di, tri,
  tetra)

Examples Xenon hexafluoride Carbon
disulfide Trisilicon pentabromide
XeF6
CS2
Si3Br5
Remember that something like K2SO4 is NOT
dipotassium sulfate. Why?
K2SO4 is ionic and NOT molecular.

How can you distinguish between an ionic and a
molecular compound?
Look for the presence of a metal ion.
If there is a metal ion, the compound is ionic
and you should use the rules for naming ionic
compounds. If there are only nonmetals present,
the compound is molecular and you should use the
rules for naming molecular compounds.

Naming Oxoacids
The 5 ic acids
Sulfuric H2SO4 Nitric HNO3 Chloric HClO3 Phosph
oric H3PO4 Carbonic H2CO3
You will need to know the name AND formula. Pay
particular attention to the number of oxygens
each acid has in its ic form.

Now what about cases like these H2PO4-
HPO4-2 PO4-3
From what we know so far all of these would be ???
phosphate
Well they cant all be phosphate so we need a
method to deal with multiple hydrogens
H2PO4-
HPO4-2
PO4-3
Dihydrogen phosphate
phosphate
Hydrogen phosphate
Example Na2HPO4
Sodium hydrogen phosphate
Note These are the ONLY examples of where there
will be three parts of a name.
