Tell what is meant by each of the following terms. (c) Band gap

Video transcript

Hello everyone today we are being given the following question. Give the definition for band gap. Well, in simplest terms, a band gap is essentially the energy difference between two different bands. So there's an injured difference between the valence band. So the valence band and the conduction band. And so what are these two types? So when we defined what a band gap is, let's define what a valence band and what a conduction band are. So a valence band is simply the lower energy bonding molecular orbital. And if that's the case then conduction bands should be the opposite, which would be higher energy anti bonding molecular orbital, so higher energy anti bonding molecular orbital's. And so to just reiterate a band gap is just the energy difference between the valence band and the conduction band. And so with that we've answered the question overall. I hope this helped. And until next time.
