Atomic Emission Spectra
Why do we only calculate the electronic transitions (using nf and ni) for hydrogen and not for helium or mercury? (Hint: Think about the limitations of the Bohr model and what the Rydberg constant applies to)

I was having trouble with some lab question on atomic emission
spectra.
Also answer the following questions about your observations: Are the lines present in the hydrogen spectrum the same lines predicted by the Bohr model the atom? Which lines, if any, are missing? Why might there be lines missing? Compare the spectral lines from your unknown substance to the other spectra you observed. Based on these comparisons, what is the identity of the unknown substance? Are there any general...

Chapter 30, Problem 59
The Bohr model can be applied to singly ionized helium He+
(Z=2). Using the model, consider the series of lines that is
produced when the electron makes a transistion from higher energy
levels into the nf = 4 level. Some of the lines in the series lie
in the visible region of the spectrum (380 nm - 750 nm). What are
the (a) minimum value and (b) maximum value of ni for the energy
levels from...

Calculate the energy of electron transitions in a one-electron (bohr) system Question What is the wavelength of a photon that will excite an electron from n=3 to n=5 in a hydrogen atom? Use R∞=2.179×10−18J for the hydrogen atom Rydberg constant. Use h=6.626×10−34 Js for Planck's constant. Use c=2.998×108ms for the speed of light.

Problem 2: Helium Spectra In helium, there are two electrons, which makes the math in finding their energy levels much more complicated. As a first approximation to that math, we can use Bohr energy levels with Z = 1.34 for the neutral helium atom (ie when both electrons are present), and Z = 2 for the singly ionized helium atom (ie when only one electron is present). The lower Z value for the neutral helium atom can be thought of...
