What makes metal conductors?


What makes metal conductors?

Metals conduct electricity by allowing free electrons to move between the atoms. These electrons are not associated with a single atom or covalent bond. Thermal conductivity is similar to electrical in that exciting atoms in one section works to excite and vibrate adjacent atoms.

Why are metals good conductors of current?

The electrons present in the outermost shell of the metal are very loosely bound because the nucleus has very little attraction on the outermost shell electrons. So, the metals conduct electricity due to the presence of free electrons. So, metals are good conductors of electricity because metals have free electrons.

Why are metals good thermal and electrical conductors?

Answer: Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions.

What kind of material makes a good conductor?

Most metals are considered to be good conductors of electrical current. Copper is just one of the more popular materials that is used for conductors. Other materials that are sometimes used as conductors are silver, gold, and aluminum.

What are characteristics of conductors?

Properties of Electrical Conductor

  • A conductor always allows the movement of electrons and ions in them.
  • The electric field of a conductor is zero allowing electrons to flow within them.
  • The charge density of a conductor is zero.
  • Only on the surface of the conductor, free charges exist.

What makes metals good conductors of electricity Class 10?

Complete answer: Metals can lose their electrons as the constituting electrons are held loosely in an atom. Basically, they are good conductors of electricity as they have a lattice of atoms with free electrons.
