The coinage metals have the highest electrical and thermal conductivities of all the metals, and they are also the most ductile and malleable. With an ns 1 (n − 1)d 10 valence electron configuration, the chemistry of these three elements is dominated by the +1 oxidation state due to losing the single ns electron.
