Ignoring any selection rules, how many lines will it have in its emission spectrum?

The number of lines in a spectrum is dependent upon the material being tested. Elements are often the test subject, but (then again) planets and stars have spectra of their own. On an elemental level, a spectrum is based on the number of electron excitation possibilities. More complex structures have much more complex spoectral determinations. Spectral evidence, however, should never be admissible in court!

The answer is a 5/20 because if u add all of the marbles there are 20 and there are 5 red marbles so 5/20 is the answer mark as brainliest
