Understanding Ionic and Covalent Bond Naming Conventions
This guide outlines the naming conventions for ionic and covalent bonds. For covalent bonding, elements are named based on their positions in the periodic table, using Greek prefixes to denote quantity, with "-ide" suffixed for the second element. The prefix "mono-" is omitted for the first element when it is singular. In contrast, ionic bonds do not use prefixes; instead, they directly name the metal and add "-ide" to the nonmetal. Practice examples and naming rules for both types of bonds are included to enhance understanding and application.

Naming Ionic and Covalent
Naming Covalent Bonds • Element in “leftmost” column goes 1st • **if elements are in the same column, then the lower atomic # goes 1st • The 2nd element ends in –ide • Greek prefixes are used to show the number of each element
Covalent Bonding ** SEE PAGE 33 Exception: Mono- is dropped on the 1st element (if there is just one of them!!!)
Practice: Name the following CCl4 P2O5 CO SO2
Practice CCl4 = carbon tetrachloride P2O5 = diphosphorouspentoxide CO = carbon monoxide SO2 = sulfur dioxide
Naming Ionic Bonds • There are no Greek prefixes • Write the name of the metal as it is shown on the periodic table • Write the name of the nonmetal with –ide at the end • Practice • Li2S • Ag2S • MgCl2
Answers • Li2S = Lithium sulfide • Ag2S = Silver sulfide • MgCl2 = Magnesium chloride
Try Some- Covalent • Draw the molecule and then write the name of the following • CH4 • C2H6 • H2O • CO2 • C4H10
