Transcript of Nomenclature

Nomenclature
RULES
Depend on the type of compound you have
Naming binary compounds
3 different types
Nomenclature
a set or system of names or terms
Polyatomic Ions
In chemistry the IUPAC sets the rules for naming inorganic and organic compounds.
IUPAC
the process explained in the rest of the video applies only to organic molecules

we are concerned with INORGANIC MOLECULES
Binary compounds*

Ternary Salts

*today
Type

From the table you memorized
ACIDS
Have H+ and are
aqueous
Binary acids
Oxyacids

Now that you know how to name it, lets take the name and write the formula
Writing formulas

the PRINCIPLE applies to the writing of any type of formula
