Study Notes
Atomic Structure
- The outer shell of an atom is called the valence shell.
Electrical Conduction
- Insulators are materials that do not conduct electrical current under normal conditions.
- Semiconductors have the ability to conduct electrical current partially, but not fully.
- Conductive materials are characterized by their ability to conduct electrical current freely.
- Materials with very high resistivities and few free electrons are classified as insulators.
