Construct an approximate molecular orbital energy diagram for homonuclear diatomic F2. Considering only the valence atomic orbitals on fluorine. Show the sigma and pi interaction between orbitals of the same symmetry and then rank these on your diagram in terms of increasing energy (be sure to draw pictures of the orbital interactions or the final MOs). Write out the electron configuration and determine the bond order of F2.

1. For the homonuclear diatomic molecules across the periodic table from H2 to Nez (10 molecules in all), make a MO diagram like the figure, and fill in the electrons. Be sure to get the order of the orbitals correct (see Fig. 11.14 of textbook). For each molecule, give the bond order and whether or not it's paramagnetic (unpaired spins). I know this seems like a pretty basic question, but it's important for chemists to have this model embedded in...
