Jul 13, 2018· Why do ionic compounds are poor conductors of electricity - Find out more explanation for : 'Why do ionic compounds are poor conductors of electricity' only from this channel
Electrical conductivity in metals is a result of the movement of electrically charged particl The atoms of metal elements are characterized by the presence of valence electrons - electrons in the outer shell of an atom that are free to move about
Of course some of the best electrical conductors that are known are ceramics, many copper oxide based pervoskites (YBCO, BSCCO) are high temperature superconductors
Poor conductors of electricity include plastics, woods and gases, in other words, anything that is not a metal Poor conductors of heat include foam, air and some fabrics, such as felt Plastic for example is a poor conductor because it is an insulator Plastic is made up of a substance that dose not allow the flow of electrons
