2. 7 . A particular atom emits a photon of wavelength 489 nm when one of its electrons Bohr postulated quantized atomic orbits by suggesting that observed line spectra undergoes a transition from one stable energy level to another. If the final energy correspond to level has an energy of -5.88 ev, then the energy of the initial level is energies created by combining protons and neutrons in the nucleus 3.34 eV the resonant transfer of energies between electrons and protons 2.64 eV the energies of each electron in the atom 8.42 eV energy absorption or emission when electrons make a transition between 6.10 ev stationary states 5. A proton that is accelerated to 1.07 x 10 m/s experiences a radius of deflection of 3. Use the following evidence from a Millikan oil-drop experiment to determine the 14.0 cm in a magnetic field of 80 mT. The charge-to-mass ratio for the electron is a.bc x 10 C/kg. The values of a, b, c, and d are number of excess elementary charges on a charged sphere suspended between digit answer) .
