The sum of IE1through IE₄ for Group 4A(14) elements shows a decrease from C to Si, a slight increase from Si to Ge, adecrease from Ge to Sn, and an increase from Sn to Pb. (a) What is the expected trend for IEs down a group? (b) Suggest a reason for the deviations in Group 4A(14).(c) Which group might show even greater deviations?

Use the Aufbau principle and its associated mnemonic device: Predict the electron configuration of titanium (Z = 22). (a.)First, draw/create the mnemonic device for the Aufbau principle (b.) From part (a.), write out your answer in the form 1s22s22p6etc. (c.) Although it is a “transition metal” and more complicated than, say, chlorine, predict the most-common oxidation state of titanium atoms (note that Cl atoms have an expected oxidation state of -1, e.g., we expect Cl1- when bonded with a different type of atom, say sodium, Na1+ ).
