I still don't understand why the two atoms sharing an orbital is of lower energy. Why is there less potential energy when there is a bond (when the electrons are in between the two atoms) as compared to the potential energy when the atoms are separate and in their lowest energy state? Are...

Why does a filled energy level have a lower energy than a partially filled energy level?

I don't understand why the discovery of quantum tunneling had to be made in order to make use of a concept such as the one that the scanning tunneling microscope uses. For example, a STM scans surfaces and the electrons from the sample tunnel through the potential energy barrier of the space...
