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) . (Record your 4 parallel plates m = 4.2 x 10-15 kg Your answer: COO V = 430 V d = 0.50 cm Use the following information to answer the next question Selected Energy Levels in a Lithium Atom O 20 n =4 -0.8 eV 3 n = 3 -1.7 eV 300 n = 2 --3.6 eV 15 4. -5.1 eV A ball with a mass of 0.100 kg is thrown at a speed of 24.7 km/h. The de Broglie n = 1 wavelength of this ball, expressed in scientific notation, a.b x 10-cd m. The values of a, b, c, and d are (Record your 4 digit answer) 6. When an electron in a lithium atom drops from the n = 3 energy level to the n = 1 energy level, the frequency of the emitted photon expressed in scientific notation, is Your answer: 0 0 a.b x 10cd Hz.
