Naming Binary Ionic Compounds

Review Ionic Compounds: A compound composed of oppositely charged ions. Many are used to produce paper The pulp and paper mill in Thunder Bay

Periodic Table and Ion Formation

Valence electrons An electron in the outermost occupied energy level.

Naming Binary Ionic Compounds There are two ways to identify a compound: Chemical Name Chemical Formula IUPAC International Union of Pure and Applied Chemistry Binary Ionic Compounds Compound composed of a metal cation and a non-metal anion

Rules for Naming The first part of the name always identifies the positive ion, which is the metal cation. Thus, this part of the name is the name of the metal. The second part of the name always identifies the negative ion, which is the non-metal anion. The name of the non-metal ion always ends with the suffix ide.

Examples Magnesium and Phosphorus Sodium and chlorine Magnesium phosphide Sodium and chlorine Sodium chloride

Determining the Chemical Formula Cross-over method Identify the metal and non-metal Write the symbols Write the charges Cross over the charges from top to bottom Remove the charge Simplify the numbers and remove the 1’s
