27. The "seeing" ability or resolution of radiation is determined by its wavelength. If the size of an atom is approximately 10-10 m, how fast must an electron travel to have a wavelength smaller than that of an atom? (me 9.11x10- kg and h 6.63 x 10 J-s) a. 7.3 x 10% m/s b. 3.4 x 106 m/s c. 1.0 x 106 m/s d. 5.4 x 10 m/s 28. The ionization energy of the hydrogen atom is 13.6 eV. What...
A ground state hydrogen atom absorbs a photon of wavelength A. The atom's electron is excited to the orbital level n 6. What was the wavelength absorbed (in nm)?
An electron in an excited state of a hydrogen atom emits two photons in succession, the first at 2624 nm and the second at 97.20 nm, to return to the ground state (n=1). For a given transition, the wavelength of the emitted photon corresponds to the difference in energy between the two energy levels. What were the principal quantum numbers of the initial and intermediate excited states involved?
8. An exited hydrogen atom emits a photon having a wavelength of 388.9049 nm and the electron relaxes down to the n=2 level. What was the initial higher energy level of the electron? - hc 388.9049x10 nm -9 = -2.184x102 (12)
