Question

Please answer #35,and #39 10.35 The first ionization potentials of Na, K, Rb are 5.138, 4.341, and 4.166 eV respectively. Assume that the energy level of the outer electron can be represented by a hydrogenlike formula with an effective nuclear charge Z' and that the relevant orbitals are 3s, 4s and 5s, respectively. Calculate Z' for these atoms. 10.39 For a carbon atom in the configuration [He]2s22p2 the following term symbols are all possible: 1So, 3Po, 3 P1, 3P2, and 1 D2. According to hund's rules, which is the most stable state?
