The energy of a photon emitted when an electron underwent a transition to n = 1 energy level was 2.119x10-18 J. What was the initial energy level for the electron? 4. When performing a flame test you are told that a rubidium solution will produce a violet color, but an actual test of the solution (using the method described in the manual) produces a yellow color. Select the potential source(s) of error. Select all that apply. O The solution of rubidium was not concentrated enough. The nichrome wire was not cleaned sufficiently. There was a contaminant in the rubidium solution. O The flame used for the test was too hot.
