Lewis Structure

Today was the fist lesson of the new unit, bonding, we learned about Lewis structure and other things today. Something actually interesting that I learned is that certain atoms can go above 8 electrons, these atoms are ones in the P block in and below group 3 however the most common expanders are Sulfur, Phosphorus, Xenon, and Krypton.

A good example of a common expander
