    Hey guys!
    Could any of you answer this question which is really bugging me?

    Why is Copper such a good conductor of electricity?
    (I mean, other than the same old explanation of delocalised electrons; why is Cu particularly good at it?)

    Thanks in advance!

    Not sure how in depth you want this, but Cu is a particularly good conductor due to its atomic structure. With an atomic number of 29, it has a single electron on its own in its outer shell, which is extremely easy for it to let go of, which can then set off a chain reaction of electrons detaching (which produces the electrical current). Also, because of its cubic lattice structure, there is little distance for each free electron to go to move between atoms, so it's easy for them to share electrons.

    It's also a very ductile material, which while doesn't explain fully why it's a good conductor, it does explain why it's a popular material for electrical wiring. (Plus the fact it's cheap, and has low resistance.)
