- The image represents the gaps between allowed energy levels for electrons. Which model best describes this phenomenon? A. the wave model because electrons orbit the atom's nucleus in a continuous way B. the particle model because electrons are particles C. the wave model because the arrows show that the energy transfer is continuous D. the particle model because the arrows represent discrete particle-like jumpsQUESTION 12 The angular momentum of an electron in circular harmonic motion. O equals the quantum number m. O is proportional to the moment of inertia. O is proportional to Planck's constant. O none are correctIn the picture are two diagrams of the first five orbits in the Bohr model labeled A - E. The dot in an orbit is the electron. The nucleus is not shown. Shown is a BEFORE and AFTER state of the atom. An energy level diagram for the Bohr hydrogen atom is shown. Which of these events has occurred in going from the BEFORE to the AFTER state? a. a photon of energy 0.97 eV has been emitted b. a photon of energy 1.51 eV has been absorbed c. a photon of energy 1.51 eV has been emitted d. an electron of energy 1.51 eV has been emitted e. a photon of energy 0.97 eV has been absorbed
