Question
Chapter 3, Problem 86AP
Interpretation Introduction
Interpretation:
The electronegativity difference in the case of Cu-Rb and Cu-Au needs to be determined. The ionic character needs to be identified and explained.
Concept Introduction:
Electronegativity is defined as a tendency of an atom to attract the shared pair of electrons towards itself.
If the difference in electronegativity of two atoms is low, the bond formed is polar covalent. If the electronegativity difference is high, the bond become ionic in nature.

4. The common oxidation number for an alkaline earth metal is +2.
(a) Using the Born-Mayer equation (for determining the lattice enthalpy) and a Born-Haber
cycle (draw it), show that CaCl is an exothermic compound (negative AHf). Make a
reasonable prediction to estimate the ionic radius of Ca (explain your reasoning). The
sublimation (atomization) enthalpy for Ca(s) is 178 kJ/mol.
(b) Show that an explanation for the non-existence of CaCl can be found in the enthalpy
change for the reaction below. The AHf for CaCl2(s) is -190.2 kcal/mol.
