1) Click on one of the following unknown orbital images A-H. Correctly identify them from the possibities below comparing them to the possibities in the Orbitron link: http://winter.group.shef.ac.uk/orbitron/ or the Orbital Central link: http://www.orbitals.com/orb/orbtable.htm The computational files used in this exercise are the work of Professor W.R. Salzman, University of Arizona

2) Complete the Atomic Orbitals Websheet form and return to Dr. R. correctly identifying the respective type of orbital and corresponding n, l, and m quantum numbers, for example: K, Type = s, n = 1, l = 0, and ml = 0. NOTE: the value for n may be difficult to determine from the orbital's visual view, a reasonable estimation of a single n value or possible, acceptable n values is ok. Also, the image you first see before moving the orbital is positioned correctly relative to the x, y, and z axes, which is critical to determining a correct value of ml, but since many of these orbitals are degenerate, i.e. energies/wave functions are the same for any directional axis, providing all possible, acceptable ml values for l is ok. Consider the following possibilities for the unknowns: 2s, 2p, 3p, 3d z2, 3d xy, 3d xz, 3d yz, 3d x2-y2, 4f z3, 4f xyz, 4f z(x2-y2), 4f x(z2-y2), 4f y(x2-z2)] or none of the above.
