How do the allowed orbits for electrons in atoms differ from the allowed orbits for planets around the sun? Explain how the correspondence principle applies here.
Hydrogen gas can only absorb EM radiation that has an energy corresponding to a transition in the atom, just as it can only emit these discrete energies. When a spectrum is taken of the solar corona, in which a broad range of EM wavelengths are passed through very hot hydrogen gas, the absorption spectrum shows all the features of the emission spectrum. But when such EM radiation passes through room-temperature hydrogen gas, only the Lyman series is absorbed. Explain the difference.
Calculate the binding energy in eV of electrons in aluminum, if the longest-wavelength photon that can eject them is 304 nm.
Suppose the velocity of an electron in an atom is known to an accuracy of 2.0103 m/s (reasonably accurate compared with orbital velocities). What is the electron's minimum uncertainty in position, and how does this compare with the approximate 0.1-nm size of the atom?
Show that (13.6eV)/hc=1.097107m=R (Rydberg's constant), as discussed in the text.
Construct Your Own Problem The solar corona is so hot that most atoms in it are ionized. Consider a hydrogen-like atom in the corona that has only a single electron. Construct a problem in which you calculate selected spectral energies and wavelengths of the Lyman, Balmer, or other series of this atom that could be used to identify its presence in a very hot gas. You will need to choose the atomic number of the atom, identify the element, and choose which spectral lines to consider.
What is the wavelength of an electron accelerated through a 30.0-kV potential, as in a TV tube?
Why are X-rays emitted only for electron transitions to inner shells? What type of photon is emitted for transitions between outer shells?
Explain the connection between Planck's hypothesis of energy quanta and the energies of the quantum harmonic oscillator.
If an atom has an electron in the n=5 state with m1=3, what are the possible values of l ?
Integrated Concepts Calculate the velocity of a star moving relative to the earth if you observe a wavelength of 91.0 nm for ionized hydrogen capturing an electron directly into the lowest orbital (that is, a ni= to nf=1, or a Lyman series transition).
