(See attached file for full problem description with proper symbols) --- 1. A hydrogen atom in a certain excited state has its electron in a 5f subshell. The electron drops down to the 3d subshell, releasing a photon in the process. a) For each of these subshells, give the n and l quantum numbers, and give the range of possible ml quantum numbers. b) Determine the wavelength of light which would be emitted by this process. c) The hydrogen atom now has a single electron in the 3d subshell. Calculate the energy (in kJ/mol) required to ionize this (excited state) hydrogen atom. (This is the energy required to remove the electron completely from the atom.) d) The photoelectric bindin... click for more

(See attached file for full problem description) --- 2. For each of the following orbitals, provide a perspective sketch of the orbital in the Cartesian x, y, z coordinate system. Determine the number of angular nodes and the number of radial nodes in the orbital, and describe where those nodes fall. (For instance, the 2px orbital has an angular node in the yz-plane.) a) 1s b) 3pz c) 3dz2 d) 3dxy ---

(See attached file for full problem description) --- 3. a) Write the electron configuration of xenon. You may use the previous noble gas. b) Xenon can absorb energy and become "excited" into a higher energy state: Xe (g) Xe* (g) (This process requires 801 kJ/mol.) The excited xenon atom, Xe*, is similar to xenon, but the outermost electron has been promoted up into the next available subshell. Give its electron configuration.
