Consider a hypothetical X+Y− ion pair for which the equilibrium interionic spacing and bonding energy values are 0.38 nm and –5.37 eV, respectively. If it is known that n in Equation 2.17 has a value of 8, using the results of Problem 2.18, determine explicit expressions for attractive and repulsive energies EA and ER of Equations 2.9 and 2.11. En = -A/r + B/(r^n)

Calculate the bonding energy Eo in terms of the parameters A, B and n.
