Concept explainers
Interpretation:
The trend of decreasing lattice energies of the chlorides of the Group 2 metals compound has to be explained.
Concept Introduction:
A three-dimensional array of ions constitutes the ionic compound lattice. They are stabilized because of attractive forces oppositely charged ions that lower the potential energy. The lattice energy of strong ionic solids is often very large because of small and densely charged ions.
Lower is the potential energy of interaction and more stable is the ionic solid. Hence the compounds that have high charge density on small space are the most stable ionic solids. For example, the calcium phosphate is made up of

Chemical Principles: The Quest for Insight
- What aspect of the following Lewis structure indicates that the concept of coordinate covalency is needed to explain the bonding in the molecule?arrow_forward7.74 In a lattice, a positive ion is often surrounded by eight negative ions. We might reason, therefore, that the lattice energy should be related to eight times the potential of interaction between these oppositely charged particles. Why is this reasoning too simpler?arrow_forwardOn the basis of the electronegativity values given in Fig. 12.3. indicate which is the more polar bond in each of the following pairs. msp;a.OClorOBrc.PSorPOb.NOorNFd.HOorHNarrow_forward
- 7.84 Which of the following molecules is least likely to actually exist OF4,SF4,SeF4 , or TeF4 ? Why?arrow_forwardThe molecules BF3, CF4, CO2, PF5, and SF6 are all nonpolar, even though they all contain polar bonds. Why?arrow_forwardHow can I find the lattice energy of KBr when I have information such as entalpy of formation of KBr entalpy of sublimation of K entalpy of vaporization of Br2 bond energy of Br2 first ionization energy of K electron affinty of Brarrow_forward
- list the following ionic compounds: CsCl, ScN, MgO, LiCl, in order from smallest to largest lattice energy E and explain the order based on the strength of ionic interactions in each compoundarrow_forwardExplain the trend in electronegativity across period 3 supporting the answer with organisation of the periodic tablearrow_forward
