Visualizing Concepts

The following plot shows the potential energy of two \(\mathrm{Cl}\) atoms as a function of the distance between them.

(a) To what does an energy of zero correspond in this diagram?

(b) According to the valence-bond model, why does the energy decrease as the \(\mathrm{Cl}\) atoms move from a large separation to a smaller one?

(c) What is the significance of the \(\mathrm{Cl}-\mathrm{Cl}\) distance at the minimum point in the plot?

(d) Why does the energy rise at \(\mathrm{Cl}-\mathrm{Cl}\) distances less than that at the minimum point in the plot?

(e) How can you estimate the bond strength of the \(\mathrm{Cl}-\mathrm{Cl}\) bond from the plot? [Section 9.4]
