For 10 points, name these metals in the central block of the periodic table, which include copper and nickel.
These are the most common elements used to form carbon-carbon bonds in coupling reactions. Several of these elements take an electron or two from a higher-energy s orbital to get a round 5 or 10 electrons in another orbital. Orbitals of these elements split according to crystal field theory. These elements include the lightest elements that violate the (*) Aufbau principle. Ligands bind to these elements in colorful coordination complexes. They include the only elements with partially filled d-shells.
