3.4 Covalent Bonds and Lewis Structures - Columbia University
www.columbia.edu• In 1916 G. N. Lewis proposed that atoms combine in order to achieve a more stable electron configuration. • Maximum stability results when an atom is isoelectronic with a noble gas. • An electron pair that is shared between two atoms constitutes a covalent bond. The Lewis Model of Chemical Bonding
Drawing Lewis Structures to Determine Molecular Geometry ...
thomaschemistry.weebly.comDraw Lewis structures AND predict the molecular geometry of the following compounds or polyatomic ions: 1. CCl4 Tally the valence electrons C = 1 × 4 = 4 Cl = 4 × 7 = 28 Total: 32 valence electrons or 16 pair C is in center with 4 Cl’s around—this uses 8 electrons or 4 pair. We still have 12 pair—place 3 pair on each terminal Cl atom.

LEWIS STRUCTURES General Rules for Drawing Lewis Structures
clas.sa.ucsb.edu7. In drawing Lewis structures for relatively small molecules and polyatomic ions, the structures tend to be more stable when they are compact and symmetrical rather than extended chains of atoms. EXAMPLE: Write the Lewis structure for CH2O where carbon is the central atom. Step 1: Determine the total number of electrons available for bonding.
