Beautiful! As a doctoral level scientist I compliment you on your very clear model. I wish when in School,and undergraduate someone would have taught me that way! It was mostly throwing concepts in very poorly planned lectures & the students were very frequently told " you'll eventually will figure it out"

Thanks for the video! I'm a little confused at <a href="#" class="seekto" data-time="160">2:40</a>, the writing points to the band with a single electron and shows "valence band = outermost (highest) band filled with electrons (filled = all states occupied)", but in this case what is "state"? Are all states occupied in this band if there is only a single electron? I would assume "all states occupied" meant all electron holes occupied in that band with no electrons in any further outer bands but maybe I'm misunderstanding "state". Thanks!
@brandynskulina7074

Yes, all electron holes occupied, in this element there is only one electron in the outermost shell. In other elements there could be more electrons in that shell and in turn have more states possible to be occupied. Hope this helps!

The Valence Band is the shell that contains the outermost electron in an atom in the base energy state. The Conduction Band is the shell an excited electron can move UP into while still remaining associated to its atom. An electron that absorbs enough energy to be ejected from the atom leaves the atom in an ionic state. Once a valence electron moves into the conduction band, a voltage can replace an electron in the Conduction Band with an electron from a neighboring atom. This constant movement of electrons is an electrical current. If the Valence Band and Conduction Band overlap, a Valence Electron requires little voltage to move electrons from one atom to the next. Most diagrams show the Valence and Conduction Bands overlapping within the same atom in a metal, but a better understanding is that the Conduction Bands of neighboring atoms overlap. It’s more like a group of neighboring metallic atoms share the SAME Conduction Band which is what makes them good electrical conductors. Think of a section of sidewalk. If they are right next to each other, you can still see that they are sections, but for all intents and purposes, they all make ONE sidewalk. This allows you to walk (low energy) from one to the next. These are conductors. However, if you remove every other section, you know have to jump (higher energy) from one to the next. These are insulators. If you remove every other sidewalk section, but you install a curb along side the sidewalk, you can step on one sidewalk section with one foot, and on the curb with the other foot and the next sidewalk section with your first foot. This is a semiconductor (sidewalk sections) with a dopant (curb). Without a dopant, the semiconductor is an insulator. With the dopant, the semiconductor is a conductor.

Why sodium's outashell is valence and conduction band at the same time and chlorine has additionel shell which is labeled as conduction band? Because sodium's outashell electron has potentian energy (they don't need to go to next shell) and cholorine's electrons tigtly bounded to nucleus but can go up to next shell?

How is this HS physics? Im taking my undergaduate upper division experimental lab course and Im "learning" about this stuff. Nonetheless, amazing video. Was confused what what bands have to do with conductors/insulators, but I see now. Conductors have overlapping valance and conduction bands, so free electrons in the valance shell can move. "Inchulators" have a huge gap energy so those electrons will never conduct since theyre tightly bound to the atom. No electron motion.

When electron are in the conduction band, they are still part of the atom they came from? What if it gets more and more energy, can they jump to some "next band"?

the conduction band in a semiconductor means that they can "conduct" which is to move freely among atoms, so they are no longer associated with their home atom.

@anonymous.youtuber

It has to do with the difference in behavior between an individual atom (like in a gas state) and a crystal, where the atoms are interacting. In an individual atom energy levels are discrete. In a crystal there are many more levels. The many levels form a “band”. The band is not a physical space, it is what you see in a diagram, a collection of many possible energy levels. The problem with explaining things at this level, you need somewhat simplistic models of reality to get your point across. These models are a representation of reality, not reality itself. The representation of an atom as a kind of mini solar system is also just a model that helps explaining the properties of the atom. In that model, the shells don’t represent an real trajectory of electrons, but they symbolize the discrete energy levels the electrons can have inside the atom.
