4 The Covalent Bond The type of electrical attraction in which atoms are held together by their mutual attraction for shared electrons. There are two electrons within a single covalent bond. Copyright © 2007 Pearson Education, Inc., publishing as Pearson Addison Wesley

5 The Covalent Bond The type of electrical attraction in which atoms are held together by their mutual attraction for shared electrons. There are two electrons within a single covalent bond. The covalent bond is represented using a straight line. Copyright © 2007 Pearson Education, Inc., publishing as Pearson Addison Wesley

14 Copyright © 2007 Pearson Education, Inc., publishing as Pearson Addison Wesley Naming Compounds Guideline 1 —Start with the element farthest to the left in the periodic table. —For the element to the right, add the suffix -ide. Guideline 2 —With different possible combinations of elements, use prefixes to remove ambiguity.
