1. Stability in Bonding

2. As we go across the Groups in the periodic table
Elements become more stable
Observe the number of valence electrons are in Group 1 vs Group 7

3. This is due to the # of valence electrons

4. As you increase the Group # (Column) elements are more stable Analogy
Independent leaders on the right
Team oriented on the left

5. So What’s the Magic Number?
So some elements are more happy in a compound
This is ultimately to fill their valence shell
Dihydrogen Oxide
Sodium Chloride
Depends on the energy level
