Explain why the effective nuclear charge increases across a row for the main group elements, but is nearly constant across a period in the transition metals. Explain why transition metals do not show the same strong trend in atomic radius as the main group elements (and even start to get larger across the row). Explain why the ionization energies of the transition metals are very similar to each other and do not follow the same trends as the main group...

5. Using Slater’s rule, calculate the effective nuclear charge by a 2p electron in each of carbon, oxygen and nitrogen. Atomic Radii increase in the order O → N → C. The ioniza on energies vary in that they increase in the direction C → O → N. It would seem that we could use Zeff and Atomic Radius as good predictors of ionization energy. Does this work here? Why or why not?
