Question

All parts of this question refer to neutral atoms in their ground states.

a) What are the principal and orbital quantum numbers (n and l) of all the electrons in aluminum (Z=13) atoms? Please use the standard notation for specifying electron configurations in atoms.

b) Estimate (and explain briefly) the ionization energy for the least tightly bound electron in a lithium (Z=3) atom.

c) Estimate (and explain briefly) the energy that it would take to remove all the electrons from a lithium atom.

d) If a magnetic field of 2T is applied to lithium atoms, explain (as quantitatively as you can) what happens to the ground-state energy level corresponding to the least tightly bound electron. e) What happens to the ground-state energy level corresponding to the least tightly bound electron in a neon (Z=10) atom under the application of the same external 2T magnetic field?
