From molecules to solids: Lewis structures

In-Class Activity

Submitted by Barbara Reisner, James Madison University

I have students construct Lewis structures on the board starting at the noble gases and working backwards to the group 14 elements.  We talk about both second period then heavier elements.  As we move across the period we transition from molecular solids to extended solids.  

This is a nice transition from molecular chemistry to extended compounds.  I use this as a bridge into the solid state portion of the course because it allows me to review Lewis structures, trends in bond energies, and provide some descriptive chemistry information. 

 Need to think about assessment.

Equipment needs: 
CrystalMaker or a viewer to see the files that I'll eventually construct.
