For two ionic solids, `CaO` and `KI`, which of the following

WebA relatively large difference between the electronegativities of the two elements indicates that one element has a tendency to form cations and the other has a tendency to form anions. The particles in solid KI, a stable ionic compound, are arranged to maximize coulombic attractions while minimizing coulombic repulsions among the particles. WebDue to lower lattice enthalpy of KI as compared to CaO, the melting point of KI is lower than that of CaO. KI is ionic, so insoluble in benzene.

WebTo form the Cs 2+ ion from Cs +, however, would require removing a 5 p electron from a filled inner shell, which calls for a great deal of energy: I2 = 2234.4 kJ/mol for Cs. Furthermore, forming an F 2− ion is expected to be even more energetically unfavorable than forming an O 2− ion. WebWhereas lattice energies typically fall in the range of 600–4000 kJ/mol (some even higher), covalent bond dissociation energies are typically between 150–400 kJ/mol for single bonds. Keep in mind, however, that these are not directly comparable values. For ionic compounds, lattice energies are associated with many interactions, as cations ...
