(a)
Interpretation:
The name of the ionic compound Na2O needs to be determined.
Concept introduction:
Ionic compound is a combination of a cation (positively charged ion) & an anion (negatively charged ion). This combination results in a charge neutralized, stable chemical species.
There is a specific pattern to name an ionic compound. Usually in a formula of an ionic compound, cation is presented on the right side, while anion is in the left side.
Naming of cations
- Naming of the cation is very simple. Just the name of the metal element is written.
- Sometimes there are some metals that form different cations. In that case after the cation name, the charge should be indicated in roman numbers, with in the brackets.
Naming of anions
To determine the name of the monoatomic anion (anion which has only one type of atom), the ending name of the elemental anion should be removed to replace by "ide".
(b)

Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle to obtain the value of lattice energy for PbS. You will need the following data following data: AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol; S¯(g) (g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formation are calculated beginning with the elements in their standard states (S8 for sulfur). The formation of S2, AHF: S2 (g) = 535 kJ/mol. Compare the two values, and explain the difference. (8 points)arrow_forward
