Calling all Chemists

A quickie, but i can't seem to find an answer,

Why does the resistance of the following elements increase?

As (aresenic)
Sb (antimony)
Bi (bismoth)

Because in actual fact they get more metallic as you go down this group (15) but still the resisitivities increase??

Thanks

Haven't done chemistry in a couple of years, but do they have less free electrons?

Because they hate each other :mad:

larger ions impeding the electron flow?

that's more physics than chemistry though, no?
