a) An electron in a hydrogen atom has energy E= -3.40 eV, where the zero of energy is at the ionization threshold. In the Bohr model, what is the angular momentum of the electron? Express your result as a multiple of ħ. Ans. b) What is the deBroglie wavelength of the electron when it is in this state? Ans. c) When the electron is in this state, what is the ratio of the circumference of the orbit of the electron to the deBroglie wavelength of the electron? Ans. d) The electron makes a transition from the state with energy E= -3.40 eV to the ground state, that has energy -13.6 eV. What is the wavelength of the photon emitted during this transition? Ans.
Electrons in multielectron atoms absorb X-rays at characteristic energies, leading to ionization. The characteristic energies for each element allow scientists to identify the element. For magnesium, X-rays with λ = 952 pm are required to selectively eject an electron from the n = 1 energy level, and X-rays with λ = 197 nm remove an electron from the n = 2 energy level. Calculate the frequency and energy of those X-rays. Why are the wavelengths and energies different for the two electrons.
The Bohr model of the single-electron, many-proton ion predicts the emitted/absorbed photon wavelength for an electron transition between the n,and n2 energy levels is = where R. = 1.097 × 107 m¬1 is the Rydberg constant and Z is the atomic number (the number of protons found in the nucleus). Calculate the ground state energy of a triply ionised beryllium atom, Be3+ (a beryllium atom with three electrons removed).
