Shielding and Effective Nuclear Charge 1. The first ionization energy of silicon (Si) is 1.31aJ. What orbital does this concern in a ground state Si atom? Determine the Z eff for this orbital. 2. On one graph, sketch the r 2 Ψ 2 plot for the 3p orbital in silicon (Si) using a solid line and the r 2 Ψ 2 plot for the 3p orbital in germanium (Ge) using a dashed line.
