Question: 21 in an ionic bond the net potential energy between...

Question details

2.1 In an ionic bond, the net potential energy between two adjacent ions, Ex, can be represented as the sum of attractive energy (-A/r) and repulsive energy (B/r). A B r rn a) Describe the cause of the attraction and the repulsion b) Determine the minimum bonding energy, Eo, in terms of parameters A, B and n. Using calculus, think about how to mathematically find a minimum of a function Bonus Challenge: Sometimes the repulsive energy term is described as a function of a negative exponential, where D and p are material dependent constants. If the attractive energy term is the same (dependent upon coloumbic forces), determine the minimum bonding energy, Eo, in terms of parameters A, p, and ro (the equilibrium bond length). You will follow a similar procedure as part b, now with a new mathematical function.
