Free Electron (Noun)
Meaning
Electron that is not attached to an atom or ion or molecule but is free to move under the influence of an electric field.
Classification
Nouns denoting natural objects (not man-made).
Examples
- The free electron was accelerated by the electric field and gained kinetic energy as it moved through the conductor.
- In a conductor, the free electrons are able to move freely and carry electrical current.
- The presence of free electrons in a metal is responsible for its high electrical conductivity.
- The free electron was able to move freely in the metal lattice, carrying energy from one end of the conductor to the other.
- When a photon collides with an atom, it can eject a free electron, which can then participate in electrical conduction.
