Presentation Transcript

    1. 1 Chapter 6-Covalent Bonds Properties of covalent compounds A. Formed by atoms sharing electrons (still obey octet rule, but both atoms can count shared electrons as part of octet) B. Formed by nonmetal atoms reacting together-both atoms want to take electrons

    2. 2 C. Form separate molecules are amorphous-no regular shape D. Low density, M.P. & B.P. molecules have spaces between them many are flammable E. Can have liquids, gases or solids at room temperature (depends on molecule size)

    3. 3 F. Two Types of Covalent Bonds Polar Bonds electronegativity difference between 0.4 & 1.7 b. electrons unequally shared pulled to higher electronegativity have small charges on molecules c. are poor conductors if dissolved or melted d. soluble with ionic or polar (like dissolves like-both have charges)
