Copper, Silver and Gold are in the same column of the chemical element chart. (same free electron count)

In general Hyper physics states :

The general properties of metals include malleability and ductility
and most are strong and durable. They are good conductors of heat
and electricity. Their strength indicates that the atoms are difficult
to separate, but malleability and ductility suggest that the atoms are
relatively easy to move in various directions. The electrical
conductivity suggests that it is easy to move electrons in any
direction in these materials. The thermal conductivity also involves
the motion of electrons. All of these properties suggest the nature
of the metallic bonds between atoms.


Remember - the larger the atom - the further away the outer shell is from the center.
They are in weak control and are available to move or swap.
They can easily move up/down shells and on/off from atom to atom.

What is it about copper that makes it so good as a conductor of heat?

Similar q. for silver and electricity.
