2)Sulfur vapor is analyzed by photoelectron spectroscopy (PES). Measurements determine that photoelectrons associated with the 1st ionization energy of sulfur move with de Broglie wavelength λ=2.091 A˚. What is the maximum wavelength (in meters) of radiation capable of ionizing sulfur and producing this effect?

Answer 1

Multi-electron Atom Ionization Energy, Conservation of Energy, Wave-Particle Duality.

Answer 2

Remember
E(photon) = E(electron)+E(Binding)
Look also for deBroglie wave.
