Multielectron atoms: What element has a K_α line with wavelength 1.46 × 10^-11m?

Question

Quizplus · Accepted Answer

The K_α line corresponds to the transition between two energy levels in the electron configuration of a multielectron atom. The specific wavelength of 1.46 × 10^-11m corresponds to the energy difference between these two levels. By consulting a table of atomic spectral lines, we can identify the element with this specific transition. In this case, the transition corresponds to a line in the spectrum of uranium. None of the other elements listed have a spectral line with this particular wavelength.
