Would effective nuclear charge play a role in an electron's ability to change its quantum level? I had my Chemistry midterm today. There was a question that asked: Describe the bohr model similarities between H and Br3+. Also, are they similar in their spectra emission?
I answered yes with the reason that Br will have exactly one electron left over and both atoms will have the electron in the n=0 orbital. I also said that the electrons will need the same amount of electromagnetic radiation to change states. That both atoms would emit the same wavelength of photon because they both have 1 electron in the same quantum level. As a result, because the energy given off is the same, they'll both show the same color on the line spectra.
Now the part that's bugging me; even though both atoms have 1 valence electron, would Bromine's 3 protons have affected it's ability to change quantum state? To be more specific, would the 3 protons, with it's effective nuclear charge as +3 as apposed to +2, require for the electromagnetic radiation to be larger in order for it to change quantum level? Or does the effective nuclear charge not play a role in how much EM radiation is needed to change the quantum level?
I briefly glanced the text book, and the internet but couldn't find a solution.
