For your work in a mass spectrometry lab, you are investigating the absorption spectrum of one-electron ions. To main- tain the atoms in an ionized state, you hold them at low density in an ion trap, a device that uses a configuration of electric fields to con- fine ions. The majority of the ions are in their ground state, so that is the initial state for the absorption transitions that you observe. (a) If the longest wavelength that you observe in the absorption spectrum is 13.56 nm, what is the atomic number Z for the ions? (b) What is the next shorter wavelength that the ions will absorb? (c) When one of the ions absorbs a photon of wavelength 6.78 nm, a free elec- tron is produced. What is the kinetic energy (in electron volts) of the electron?

- Estimate the wavelength and energy (in eV) of a photon with which one can resolve featuresof a sample that are 0.1 nm in size. Assume that in order to resolve a feature, the wavelength mustbe smaller than the size of the feature.(b) Estimate the wavelength and energy (in eV) of an electron with which one can resolve featuresof a sample that are 0.1 nm in size.

The light wave is made of discrete photons, each with energy hf = hc/λ. An electron will either completely absorb a photon, or not at all. An electron in a metal needs an energy to leave the metal -- the work function (W). For the W given, calculate the maximum light wavelength (in nm) that will eject an electron. I will use electron-volts (eV) for energy, because the computer gives me trouble with very low numbers. hc = 1240 eV nm W = 3.9 eVarrow_forward
