Document Summary
Steps for molecular substances: determine the number of valance electrons in the. Cf4: find all the valance electrons, carbon = 4, fluoride = 7 * 4 = 28, total of 32 available electrons, knowing carbon is the central atom, distribute. Lewis formulas: multiple bonds and bond order: bond order is # of bonding electron pairs divided by the number of bonded atom pairs. Find the bond order of o2: we know there is a double bond (so 2 on the top) and one bonded pair making it 2/1 or a bond order of 2. Lewis structure for cations and anions: you do the exact same steps as before except remove electrons for cations and add electrons for anions to your available electron pool. Lewis formulas: resonance structures for carbonate: all bond lengths are different lengths depenant on where the electron is being shared, all bond orders are the same.
