Conduction electrons are the electrons in a material that are free to move and thus responsible for conducting electric current. They play a crucial role in the electrical conductivity of metals and are described by quantum mechanics, particularly in the context of the band theory of solids.

Electric current is the flow of electric charge through a conductor, typically measured in amperes. It is a fundamental aspect of electricity, enabling the operation of electrical devices and the transmission of power across distances.

electric current

Electrical conductivity is a measure of a material's ability to allow the flow of an electric current, which is determined by the availability and mobility of charge carriers such as electrons or ions. It is a critical property in determining the suitability of materials for applications in electronics, energy transmission, and electrochemical processes.

electrical conductivity

Metals are elements characterized by their high electrical and thermal conductivity, malleability, ductility, and a lustrous appearance. They are typically solid at room temperature and are used extensively in construction, manufacturing, and technology due to their strength and versatility.

Quantum mechanics is a fundamental theory in physics that describes the physical properties of nature at the smallest scales, such as atoms and subatomic particles. It introduces concepts like wave-particle duality, uncertainty principle, and quantum entanglement, which challenge classical intuitions about the behavior of matter and energy.

Band theory of solids explains the behavior of electrons in a material, forming energy bands due to the overlap of atomic orbitals in a periodic crystal lattice. This theory helps in understanding the electrical properties of materials, distinguishing between conductors, semiconductors, and insulators.
