valence of +2 and an anion with a valence of -1, the centers of
which are separated by a distance of 2.6 nm.

(a)Using the ionic radii data calculate the coulombic force of
attraction between the Mg2+ -O2- ion pair. (b) What is the
repulsive force in this case? Calculate the minimum radius ratio
for a coordination number of (a)4 and (b)6.

Calculate the energy of attraction between a cation with a
valence of +2 and an anion with a valence of -2, the centers of
which are separated by a distance of 1.3 nm.

Calculate the equilibrium distance between a Ca2+ and an O2- in
terms of [nm]

A uranium ion and an iron ion are separated by a distance of
?=23.30 nm. The uranium atom is singly ionized; the iron atom is
doubly ionized. Calculate the distance ? from the uranium atom at
which an electron will be in equilibrium. Ignore the gravitational
attraction between the particles.
What is the magnitude of the force on the electron from the
uranium ion?

(a) Calculate the Coulomb electrostatic force and electrostatic
energy between a Na+ ion and a Cl- ion at a distance of 0.22 nm. Is
this attractive or repulsive? The magnitude of the ionic charge of
Na+ and Cl- ion is 1.6 x 10-19 C. (b) Calculate the Coulomb
electrostatic energy between one casein submicelle and one Ca++
ion, assuming that the submicelle has negative charge - 1 x 10-17
C, and the separation between the centers of the submicelle and...
