why is the electrical conductivity of calcium higher than a transition element (except copper)?

This is because Transition elements have more delocalized electrons than Calcium, but they also have a smaller atomic radius than Calcium, so friction is much grater in Transition elements making transition elements have a lower electrical conductivity than Calcium. Imagine an electron trying to move around in the smaller, more packed and crowded transition element compared to the more spacious, less packed Calcium! Electricity will flow more easily in Calcium than the transition metal even though the transition metal has more delocalized electrons-why? because of less friction in Calcium.
