(2) What states are possible for a d3 configuration? Determine the Coulombic and exchange energies for each and rank the states in terms of relative energy.

(3) According to Slater’s rules, a 3d electron in Ni has a higher effective nuclear charge than a 4s electron. Is the same true for early first row transition metals? Using Slater’s rules, calculates S and Z* for 4s and 3d electrons of Sc and Ti and comment on the similarities or differences with Ni.
