Answer to relevant QuestionsWhat is the binding energy for an electron in the ground state in the following hydrogen-like ions: (a) He + (Z = 2) and (b) Li2+(Z = 3)? Light of wavelength 340 nm is incident on a metal surface and ejects electrons that have a maximum speed of 3.5 x 105 m/s. (a) What is the work function of the metal? (b) What is its stopping voltage? (c) What is its ...A photon of wavelength 320 nm is absorbed by a hydro-gen atom when the electron is in the second excited state. What is the speed of the ionized electron? How would the radius for the maximum probability in Fig. 28.3a change if the charge on the proton in the hydrogen atom were suddenly decreased? Explain your reasoning. (a) How many possible sets of quantum numbers are there for the n = 1 and n = 2 shells? (b) Write the explicit values of all the quantum numbers (n, ℓ, mℓ, ms) for these levels.
