Chapter 6 Learning Objectives

6.1 Covalent Compounds
Molecular orbital (fig. 6-2,pg.195)
Diatomic elements
Octet rule, stability, noble gas configuration,
Potential energy Curve (fig. 6-4, pg. 196), Lowest energy=most stable
Bond length (Table 6-1 pg. 197)
Bond length and bond strength inversely related
Electronegativity (Linus Pauling) and bond type (ionic, polar covalent, non-polar covalent)
Use the difference in electronegativity(Table 6-2 pg.198) values between two bonding atoms to determine bond type. Francium lowest e.n.v. (0.7) and Fluorine has the highest e.n.v. (4.0)
Use a dipole symbol,→, over polar bonds or use lower case greek delta, δ, which indicates partial.
Direct relationship between bond strength and polarity (dipole moment)
Polarity is measured finding the difference in electronegativity values
