Cu

Explanation:

The electrons in copper are delocalized in a "sea of electrons" therefore they move easily between atoms becoming an excellent conductor. One has to remember the valence shell of Copper is 4s1 hence its easy movement.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
