# Electrical Conductivity of Copper, Gold And Silver

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.
