Chapter 30, Problem 59

The Bohr model can be applied to singly ionized helium He+ (Z=2). Using the model, consider the series of lines that is produced when the electron makes a transistion from higher energy levels into the nf = 4 level. Some of the lines in the series lie in the visible region of the spectrum (380 nm - 750 nm). What are the (a) minimum value and (b) maximum value of ni for the energy levels from which the electron makes the transitions corresponding to these lines?

    Problem 2: Helium Spectra In helium, there are two electrons, which makes the math in finding their energy levels much more complicated. As a first approximation to that math, we can use Bohr energy levels with Z = 1.34 for the neutral helium atom (ie when both electrons are present), and Z = 2 for the singly ionized helium atom (ie when only one electron is present). The lower Z value for the neutral helium atom can be thought of...

    When an electron of an excited hydrogen atom descends, from an initial energy level (ni) to a lower (nf), characteristic electromagnetic radiation is emitted. The Bohr model of the H-atom allows the calculation of ?E for any pair of energy levels. ?E is related to the wavelength (?) of the radiation according to Einstein's equation ( ?E = [(hc)/?]). Distinct series of spectral lines have been classified according to nf: Lyman series:nf=1 (91<?<123 nm; near-UV). Balmer series:nf=2 (365<?<658 nm; visible)....

    Although the Bohr model was very successful in accounting for the line spectrum of hydrogen, from what limitations did it suffer? It failed to predict the line spectrum for multi-electron atoms. It incorrectly proposed that electrons could reside between orbital's. It only accurately predicted the visible series of lines in the line spectra of atoms, but not the ultraviolet or infrared series. It incorrectly proposed that electrons move in fixed, defined orbits. It did not explain the quantized nature of...
