Question

5. The lines observed in the hydrogen spectroscope
to
A. loss of electrons from the atom
B. loss of neutrons from the atom
C. emission of energy by proton transitions
D. emission of energy by electron transitions.​

Answer 1

Answer:

All observed spectral lines are due to electrons moving between energy levels in the atom. The spectral series are important in astronomy for detecting the presence of hydrogen and calculating red shifts. Further series for hydrogen as well as other elements were discovered as spectroscopy techniques developed.
