What is the energy of the photon that, when absorbed by a hydrogen atom, could cause the following? (a) an electronic transition from the n = 1 state to the n = 5 state Answer:_______ eV(b) an electronic transition from the n = 3 state to the n = 7 state Answer:_______eV
What features of the Bohr model of hydrogen are consistent with the later, full quantum mechanical analysis? 1. When the atom drops from a higher energy state to a lower energy state, a photon is emitted with the energy corresponding to the difference in energy levels. 2. K+U is (-13.6/N2) eV. 3. The energy is quantized. 4.The electron moves in distinct circular orbits. 5. The angular momentum in the ground state is h/2. 6. The angular momentum is quantized. 7. Higher energy states correspond to a larger size of the atom. 8. A photon can be absorbed by the atom if the photon's energy corresponds to the energy necessary to jump to a higher energy level.
An electron in a hydrogen atom undergoes a transition from an energy level with n=4 to an energy level with n=2. Calculate the energy change (in electron volts) during this transition. Given: Rydberg constant R_H=13.6 eV.
