Electrical Conductivity of Copper, Gold And Silver

  1. Apr 17, 2015 #1
    Copper ::: 60.7 x 106 S m^-1
    Silver :::62.9 x 106 S m^-1
    Gold :: 48.8 x 106 S m^-1

    Why is the electrical Conductivity of these elements this way? I mean down the periodic table it should increase in case of GOLD but instead Gold is have far less value of Electrical Conductivity.

    What factor should cause it to increase going down the periodic table then?

    There's really no easy way to explain the differences, as they are based on the particular electron configuration of each atom and how they bond together in a metal.
    One way of calculating the conductivity is based on the density of free electrons in the metal. Check out the following link (specifically the 3rd section): http://hyperphysics.phy-astr.gsu.edu/hbase/electric/ohmmic.html
