What are the n and l quantum numbers for Cadmium?
What is the energy of the n = 4 level of a H atom(in Joules)?
What is the energy of the n = 9 level of a H atom(in Joules)?
What is change in E for the n = 4 to n = 9 transition (in Joules)?

1) Well, a more appropriate question would be some thing like " What are the n and l quantum numbers for the electrons of highest energy in the ground state of Cadmium?". For Cd, the n =1, 2, 3 orbits are completely filled. The n = 4 and l = 3 "4f" orbit is empty, since its energy level is higher than 5s orbit. The electrons of highest energy in the ground state of Cadmium is n=5 and l=0, the 5s orbit.
(2) and (3) By using the Rydberg equation, energy level must be given by: E = -hR/n^2
where h the Plank constant, R the Rydberg constant, and n the principal quantum number.
(4) Please directly calculate this from the Rydberg equation:
E = hν = hR(1/n^2-1/m^2)
I am just trying to help you. So you may easily calculate the final results by yourself. Good Luck!
