Learning Objectives
MLO4-1 Determine the polarity of a bond using differences in electronegativity to differentiate between ionic, polar covalent and nonpolar covalent bonds.
MLO4-2 Illustrate bonding or charge of an ion from its valence electrons and location on the periodic table.
MLO4-3 Apply rules for drawing Lewis structures of compounds.
MLO4-4 Determine the formal charge on the atoms in a Lewis structure to identify the most likely structure of a compound when more than one Lewis structure can be drawn.
