Question 2 (20 points) Two hypothetical elements, X and Y, have one valence electron in their outermost s shell each and react to form a XYmolecule. The atomic energies of the valence orbitals of atoms X and Yare &, =-lev and & =-3eV, respectively, and the interatomic matrix element is V. =1eV. Use the Linear Combination of Atomic Orbitals method to evaluate: a) The binding energy of the XY molecule b) The net electric charge on each of the X and Y atoms
