1. Tuesday 10/19/10

2.  Return Naming Compounds Quiz  Collect Symbol Me Projects  Lewis structures  Metallic Bonding  Hydrogen Bonding  Jeopardy Review

3.  Atoms form bonds to gain a full shell of valence electrons. (Octet Rule)  If electrons are not involved in bonding, then they are lone pairs.  Each bond is made up of 2 electrons.

4.  Count up the total # of valence electrons.  If it’s an ion, then add or subtract e - as needed.  Connect all the atoms with single bonds.  Place the remaining electrons as lone pairs around the atom.  Create double or triple bonds if there are not enough electrons to go around.  ALWAYS FOLLOW THE OCTET RULE!!!!
