- From the data in Table 14.2, predict B for DCl D is 2H.The ionisation energy of potassium is 4.34 eV and the electron affinity of chlorine is 3.61 eV. The Madelung constant for the KCl structure is 1.748 and the closest distance between ions of opposite sign is 0.314 nm. On the basis of these data, calculate the cohesive energy of KCl. Compare this with the observed cohesive energy of 6.42 eV for the ion pair and comment on the reasons for any discrepancy9B.2 Put the following species in order of increasing bond length: F2-, F2, F2+ Before solving the problem please also give a brief explanation of the concept or associated equation(s) and variables.

- X Incorrect. The net potential energy between two adjacent ions, E, may be represented by EN = = A + B ph Where A, B, and n are constants whose values depend on the particular ionic system. Calculate the bonding energy Eo in terms of the parameters A, B, and n using the following procedure: (1) Differentiate EN with respect to r, and then set the resulting expression equal to zero, since the curve of EN versus r is a minimum at Eo. (2) Solve for r in terms of A, B, and n, which yields ro, the equilibrium interionic spacing. (3) Determine the expression for Eo by substitution of ro into the above equation for EN. Which of the following equations represents the expression for Eo?

Their biochemical action is a reflection of theirorbital structure. Deduce their ground-state electron configurations.

Using data from Appendix Fand assuming that a Coulomb potential is a good approximation of the potential from K+ + Cl= to 2.67 3 10=10 m,estimate the dissociation energy of gaseous KCl into K andCl atoms (in kJ mo=1). (Note: Table 3.7 shows that aCoulomb potential is only a good approximation to thepotential between two charged atoms at long inter-atomicdistances; the percent ionic character of KCl at equilibrium is only 82%.)In the series of group 5A hydrides, of general formulaMH3, the measured bond distances are P¬H, 1.419 Å;As¬H, 1.519 Å; Sb¬H, 1.707 Å.
