Introduction to the First-row Transition Elements
WEBAbstract. The elements of the first transition series are those for which the 3d electron shell contains between one and nine electrons. Copper is included because, although its outer electronic configuration is 3d 10 4s 1, it has the 3d 9 configuration in its commonly occurring +2 oxidation state. Zinc is not normally considered a transition ...
