This video provides a brief overview of atomic make up of conductors, semiconductors and insulators. This information will give you a bit of background as to why some elements are good insulators, why some are good conductors, and why some are semiconductors.
The material is based on the excellent resource Lessons in Electric Circuits by Tony Kuphaldt which can be found here:

I apologize to anyone with a background in chemistry or atomic theory, I glossed over a lot of details in order to create some content that I think is relevant to someone just beginning to learn about semiconductor theory.
