An Ionic Bond. (a) Calculate the electric potential energy for a K$^+$ ion and a Br$^-$ ion separated by a distance of 0.29 nm, the equilibrium separation in the KBr molecule. Treat the ions as point charges. (b) The ionization energy of the potassium atom is 4.3 eV. Atomic bromine has an electron affinity of 3.5 eV. Use these data and the results of part (a) to estimate the binding energy of the KBr molecule. Do you expect the actual binding energy to be higher or lower than your estimate? Explain your reasoning.

During each of these processes, a photon of light is given up. In each process, what wavelength of light is given up, and in what part of the electromagnetic spectrum is that wavelength? (a) A molecule decreases its vibrational energy by 0.198 eV; (b) an atom decreases its energy by 7.80 eV; (c) a molecule decreases its rotational energy by 4.80 $\times$ 10$^-$$^3$ eV.

Two atoms of cesium (Cs) can form a Cs $_{2}$ molecule. The equilibrium distance between the nuclei in a $\mathrm{Cs}_{2}$ molecule is $0.447 \mathrm{nm} .$ Calculate the moment of inertia about an axis through the center of mass of the two nuclei and perpendicular to the line joining them. The mass of a cesium atom is $2.21 \times 10^{-25} \mathrm{~kg}$.

The average kinetic energy of an ideal-gas atom or molecule is \(\frac{3}{2}\) $k$$T$, where $T$ is the Kelvin temperature (Chapter 18). The rotational inertia of the H2 molecule is 4.6 $\times$ 10$^-$$^4$$^8$ kg $\cdot$ m2. What is the value of $T$ for which \(\frac{3}{2}\) $k$$T$ equals the energy separation between the $l$ = 0 and $l$ = 1 energy levels of H$_2$? What does this tell you about the number of H$_2$ molecules in the $l$ = 1 level at room temperature?

If a sodium chloride (NaCl) molecule could undergo an $n$ $\rightarrow$ $n$ $-$ 1 vibrational transition with no change in rotational quantum number, a photon with wavelength 20.0 $\mu$m would be emitted. The mass of a sodium atom is 3.82 $\times$ 10$^-$$^2$$^6$ kg, and the mass of a chlorine atom is 5.81 $\times$ 10$^-$$^2$$^6$ kg. Calculate the force constant $k$$'$ for the interatomic force in NaCl.
