Naming of Compounds

Key terms:

Writing FormulasĀ for Ionic Compounds an Intro
Chemical Nomenclature: A system such as the one approved by IUPAC

International Union of Pure and Applied Chemistry or IUPAC
An organization in Paris France which is the regulating body for naming of compounds and providing standards for measurement of other units like mass , length, time etc.

Binary compounds:
A compound formed from 2 kinds of atoms or two kinds of mono atomic ions.

Oxidation number or valency of an ion:

The number indicated on a cation or anion showing the number of electrons gained or lost also known as valency.

Tertiary compounds:
A compound composed of 3 different elements

Oxyanions:

A polyatomic ion containing oxygen.



Multivalent ions:

A cation (metal ion) capable of showing more than one valency e.g. Pb2+ and Pb4+

Classical Approach for multivalent ions:
-ous lower oxidation state Fe2+ Ferrous
-ic higher oxidation state Fe3+ Ferric

Hydrates
Tertiary ionic compounds which contain water molecules within the crystal structure are called hydrates e.g. CuSO4 . 5H2O = Copper(II) sulfate pentahydrate
