5) This question concerns the Bohr model of the atom. a) In what way is the Bohr model of the atom analogous (similar) to the model of the planets in the solar system revolving around the Sun? Explain in one or two sentences. b) In what major way is the behavior of the electrons in the Bohr model of the atom very different than the behavior of the planets in the solar system revolving around the Sun? Explain in one or two sentences. 6) In the hydrogen photon emission spectrum, the Paschen series are photon emissions which result from any electron transition to energy level nf = 3. What is the energy (in eV) of the third-longest wavelength photon emitted in the Paschen series?
