The expressions (c₁₁)² + c₁₁c₂₁S₁₂ and (c₁₂)² + c₁₁c₂₁S₁₂ for the probability of finding an electron on the H and F atoms in HF, respectively, were derived in Section 23.8. Use your results from Problem P23.21 and these expressions to calculate the probability of finding an electron in the bonding orbital on the F atom for S_HF = 0.075 , 0.18, and 0.40. Explain the trend shown by these results.

Reference problem 23.21

Evaluate the energy for the two MOs generated by combining a H1s and a F2p AO. Use Equation (23.12) and carry out the calculation for S_HF = 0.075, 0.18, and 0.40 to mimic the effect of increasing the atomic separation in the molecule. Use the parameters H₁₁ = -13.6 eV, H₂₂ = -18.6 eV, and H₁₂ = -1.75S₁₂ Explain the trend that you observe in the results.
