Nomenclature

• The International Union of Pure and Applied
  Chemistry (IUPAC) created a system of naming
  compounds.
• This system of naming chemical compounds is
  called nomenclature.
• Creates a worldwide system (like S.I. units).

3
Nomenclature

• There are three types of naming, each defined
  by where the first ion in the compound is
  located.
• These are called pink green or blue
  sections by the color of the section.
• They could also be considered S, D or P
  respectively based on electron orbital.

Pink Section

• When the first ion is from the pink section, say
  the whole name of the first ion, and replace the
  end of second with ide.
• Ex NaCl Sodium Chloride
• Ex MgF2 Magnesium Fluoride
• Ex K2O Potassium Oxide

Green Section

• The ions in the green section can have multiple
  charges.
• Therefore we have to discern their charges with
  some deduction.
• Ex CuO . . Copper must have a charge of 2 here,
  because it has a 1 to 1 ratio with O that has a
  charge of -2.

9
Green Section

• CuO continued. . .
• Since Copper has a charge of 2, you write the
  name as Copper (II) Oxide.
• Ex Fe2O3 must have a charge of 3. Therefore it
  is Iron (III) Oxide.
• Ex FeO is Iron (II) Oxide.

A.) Tin (II) Oxide
B.) Tin (IV) Oxide
C.) Tin Oxide
D.) Tin Oxide (II)
E.)
12
Blue Section

• If you havent noticed, the last ion is always
  negatively charged (blue).
• When both are from the blue, it is a covalent
  bond.
• Since these can occur in many ways, we have to
  specify how many of each atom are in the compound.

13
Blue Section

• 1 Mono 2 Di
• 3 Tri 4 Tetra
• 5 Penta 6 Hexa
• 7 Hepta 8 Octa
• 9 Non 10 - Deca

14
Blue Section

• Simply use the appropriate prefix to describe how
  many atoms are present.
• The only rule is Dont put mono on the first
  atom!
• Ex N2O4 Dinitrogen Tetroxide
• Ex CO2 Carbon Dioxide

15
Blue Section

• Si2Br6
• CO
• P2O5
• B2Si

18
Polyatomic Ions

• Sometimes multiple atoms come together to form a
  single ion.
• These polyatomic ions can then bond with other
  ions to form compounds.
• Follow the previous rules for naming.

Polyatomic Ions

• Ex NaNO3 Sodium Nitrate
• Ex CaSO4 Calcium Sulfate
• Ex FePO4 Iron (III) Phosphate
• Ex Ca(ClO3)2 Calcium Chlorate

Remember!!

• If first ion is in pink write its element name
  and replace the end of the second with ide
• If first ion is in green, only use roman numerals
  to depict its charge. I, II, III, IV, V.
• If first ion is in blue, then use the scientific
  prefixes di, tri, tetra..
