Chapter 5, Problem 5.24P

Atomic emission spectra arise from electron transitions from higher-energy orbitals to lower-energy orbitals. The blue line at 434.7 nm in the emission spectrum for mercury (Figure 5.28)arises from an electron moving from a 7d to a 6p orbital.
(a) Give the n and l quantum numbers and give the range of possible $m_1$ quantum numbers for the higher-energy 7d orbital.
(b) Give the n and l quantum numbers and give the range of possible $m_1$ quantum numbers for the lower energy 6p orbital.
(c) Calculate the energy difference between the 7d and 6p or bital in units of kJ/mol.
