$\Delta_f \text{H}^{\ominus}$ for $\text{KCl} = -436.7 \text{ kJ mol}^{-1}$; $\Delta_{\text{sub}} \text{H}^{\ominus}$ for $\text{K} = 89.2 \text{ kJ mol}^{-1}$;
$\Delta_{\text{ionization}} \text{H}^{\ominus}$ for $\text{K} = 419.0 \text{ kJ mol}^{-1}$; $\Delta_{\text{electron gain}} \text{H}^{\ominus}$ for $\text{Cl}_{(\text{g})} = -348.6 \text{ kJ mol}^{-1}$;
$\Delta_{\text{bond}} \text{H}^{\ominus}$ for $\text{Cl}_2 = 243.0 \text{ kJ mol}^{-1}$
