Write the electronic configurations of Cu+ and Zn2+ and comment on their similarity. Explain why
Cu+ can be easily oxidized to Cu2+ but an oxidation of Zn2+ to Zn3+ is not likely.
2. Do you consider Zn as a main group element or as a d-block metal? How your answer to Q. 1 does
help to justify your answer here?
3. Write the electronic configurations of Al and Ga and calculate their Zeff for a valence electron and for
a core 2p electron by using the Slater’s rule. How do you rationalize the fact that the 1st ionization
energies of these two elements are very much alike.
