What evidence indicates that electrons move around the nucleus in definite pathways?

• None of the elements emitted a full color spectrum, but rather only certain frequencies of the spectrum were given off. Since some of the spectrum is missing, this means the electrons can only emit frequencies at the fixed energy levels and not in between.

• None of the elements emitted a full color spectrum, but rather only certain frequencies of the spectrum were given off. Since some of the spectrum is missing, this means the electrons can emit frequencies of light in between the energy levels.

• All of the elements emitted a full color spectrum. (The Rainbow.)
