Question

The emission spectrum of hydrogen shows discrete, bright, colored lines. Which characteristic of the Bohr model is best supported by this observation

Answer 1

The characteristic of the Bohr model that would best support his observation is this assumption: "The energy of the electron in an orbit is proportional to its distance from the nucleus. The further the electron is from the nucleus, the more energy it has." The discrete, bright, colored lines might represent the electrons and its distance from the nucleus. The lights are caused by the energy it has.

Answer 2

In a hydrogen atom, the electrons are very far from the nucleus, which allows for such bold, powerful colors. So your answer is "The energy of an electron increases with distance from the nucleus."
