Approximately half way down "Group VIIIA Elements..." "He" Helium does not have 8 electronc in its outer shell...

Good Course.....

Hi Bertus,

yes my post should have referenced "all about circuits", on that same subject but the section addressing Band Theory and Solids"; a clarification might help,

"a substantial gap remains between the highest band containing electrons (the so-called valence band) and the next band, which is empty (the so-called conduction band)."

As a non-physicist, and if I understand this complex subject correctly, wouldn't a reference to clarify that the "next band, which is empty...) is the next highest in energy as well? Unless I am miss reading this. Adding energy to get the electron to the highest energy band or conduction band. Maybe I'm uninformed. Great site, well constructed
