2) The first ionization energies of the coinage metals, Cu,Ag, Au, are 745.5, 731.0, and 890 kJ/mol, respectively. Is this thetrend you might have expected? In the CRC Handbook ofChemistry and Physics, look up the first ionization energies of thefollowing groups of elements: (Sc. Y, La), (Ti, Zr, Hf), (Fe, Ru,Os), (Ga, In, Tl), and (As, Sb, Bi). Which groups follow the sametrend as the coinage metals? Can you suggest an explanation forthese anomalies?
