In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 2.13×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.) If you could do this without using Calculus that would be great.

Q. 3. Potassium fluoride adopts the rock salt (NaCl type) structure, with a density of 2.48 g/cm3. Using the data for the Part 4 model you constructed, calculate the expected distance between the center of the potassium ion and the center of an adjacent fluoride ion in pm. Q. 4. The diameter of a Cs+ ion is 334 pm; the diameter of a Br- ion is 392 pm. For CsBr, which crystallizes in the CsCl type structure from Part 5,...

For a K+–Cl– ion pair, attractive and repulsive energies EA and
ER, respectively, depend on the distance between the ions r,
according to EA = − 1.436 r ER = 5.8 × 10−6 r 9 For these
expressions, energies are expressed in electron volts (eV) per
K+–Cl– pair, and r is the distance in nanometers (nm). The net
energy EN is just the sum of the two expressions above (EN = EA +
ER). (a) Superimpose on a single plot...
