Metals as conductors chemistry

Web7 sep. 2024 · Some conductors has a partially filled valence band that is relatively easier to excite an electron to a higher energy level, as in a). Other conductors, such as divalent metals represented in b), can have an overlap of the empty conductive band with a totally filled valence band. WebThis is the reason why metals are generally good conductors of electric current. 2. Thermal Conductivity The thermal conductivity of a material is a measure of its ability to conduct/transfer heat. When one end of a metallic substance is heated, the kinetic energy of the electrons in that area increases.
