3 Salt is An Ionic Compound Sodium chloride or table salt is an example of an ionic compound. Copyright 2005 by Pearson Education, Inc. Publishing as Benjamin Cummings Copyright Houghton Mifflin Company. All rights reserved. 2 3

4 Naming Ionic Compounds with Two Elements To name a compound that contains two elements, identify the cation and anion. name the cation first followed by the name of the anion. Copyright Houghton Mifflin Company. All rights reserved. 2 4

5 Binary Ionic Compounds Type (I) An ionic formula consists of positively and negatively charged ions. is neutral. has charge balance. total positive charge = total negative charge The symbol of the metal is written first followed by the symbol of the nonmetal.
