6.4 LEWIS STRUCTURE DIAGRAMS Lewis Dot Structures (aka. Electron dot diagrams): Diagrams that show bonding between atoms of a molecule. How to Draw Lewis Dot - Valence E- *Must be able to find VALENCE ELECTRONS How to Draw Lewis Dot - Atoms/Ions Rules for drawing Lewis Structures of atoms: 1. Write the element symbol 2. If H: place 1 dot next to symbol; if He: place 2 dots slightly further apart 3. If up to 4 Ve-: place Ve-’s around the symbol first (alone) 4. If more than 4 Ve-, pairing of dots only after * Metals: Total # of dots/e- represent # north, south, east and west of symbol is filled of e- that can be lost * Non-metals: # of unpaired show amount that must gain to form Drawing Monatomic Ions complete octet How to Draw Lewis Dot - Molecules Lewis Dot structure for CCl4 Practice P. 331 #2a, 3a How to Draw Lewis Dot - Multiple Bonds Lewis Dot structure for CH2O Lewis Dot structure for Polyatomic ions CO32- NO31- ClO21-
