Which Property Best Accounts For The Conductivity Of Metals . Thermal conductivity • metals are good conductors of heat. The conductivity of metals is due to the electron configuration of these atoms.
What is the Periodic Table Showing? Chemogenesis from www.meta-synthesis.com
They can be drawn into wires. Metals are such good conductors due to the freedom with which the valence electron can move. Its thermal conductivity (2,200 w/m•k) is five times greater than the most conductive metal (ag at 429);
What is the Periodic Table Showing? Chemogenesis
The number of conduction electrons is constant, depending on neither temperature nor impurities. Conductivity can be defined as a measure of electrical conduction, and it shows the ability of a material to pass a current. Metals are a good conductor of electricity which means that they can conduct electricity due to the free moving electrons present in them. The free electrons of the metals can freely move throughout the solid and transfer the thermal energy at a rate very high as compared to insulators.

Insulators are materials with conductivities less than 10 −8 s/cm. They generally have fewer valence electrons than valence orbitals, so that empty orbitals in the valence shell exist. The lower the resistivity, the more readily the material permits the flow of electric charge. Metals in general have high electrical conductivity, high thermal conductivity, and high density. All metals are physically.
