Question
Chapter 12, Problem 89AP
Interpretation Introduction
Interpretation:
Among the given properties, the one that indicates the order which shows the correct trend is to be identified.
Concept Introduction:
The ability that is possessed by an atom to attract the bonding pair of electrons towards itself is known as electronegativity. The electronegativity decreases while going down the group and increases while from moving left to right in the period.
The distance between the nucleus and the valence shell electrons of an atom is known to be the atomic size of that atom. According to the periodic table, the atomic size increases while going down the group and decreases while moving from left to right in the period.

“Inert” xenon actually forms several compounds, especially with the highly electronegative elements oxygen and fluorine. The simple fluorides XeF2, XeF4, and XeF6 are all formed by direct reaction of the elements. As you might expect from the size of the xenon atom, the Xe¬F bond is not a strong one. Calculate the Xe¬F bond energy in XeF6, given that the enthalpy of formation is -402 kJ/mol.
Imagine a metallic element had been discovered and was named "Gondolium" (Gn).Gn was found to exhibit chemistry like that of an alkaline earth.
Gn(s) + F2(g) → GnF2(s)
Lattice energy for GnF2
-1950. kJ/mol
First Ionization energy of Gn
450. kJ/mol
Second Ionization energy of Gn
855 kJ/mol
Electron affinity of F
-327.8 kJ/mol
Bond energy of F2
154 kJ/mol
Enthalpy of sublimation (atomization) of Gn
195 kJ/mol
Use the above data to calculate ΔH°f for gondolium fluoride.
Consider a hypothetical ionic compound AB (comprised of A+ and B- ions).
Given the following enthalpy data and using a Born-Haber cycle calculation, predict ΔHlattice in kJ mol-1.
A(s) + B(s) → AB(s) ΔrH = -422 kJ mol-1
A(s) → A(g) ΔrH = 104 kJ mol-1
B(s) → B(g) ΔrH = 92 kJ mol-1
First ionization energy of A(g) = 505 kJ mol-1
Electron affinity enthalpy of B(g) (exothermic) = -316 kJ mol-1
