Question

please answered highlighted part very detailed, thank you.

onsider a hypothetical X-Y-ion pair for which the equilibrium interionic spacing and bonding nergy values are 0.38 nm and -5.37 eV, respectively. If it is known that exponent of the Born epulsion is n-8. The interatomic potential energy functional is given by AB E(r) = -+ r r (a) Determine the values A and B in the equation above; (b) Sketch E vs. r and on the sketch clearly mark the bond length, the bond energy, the Born repulsion due to the Pauli Exclusion Principle and Coulomb attraction contributions to EN. Also sketch FN VS. r and indicate its relation to the EN VS. ro sketch: (c) Concisely describe, compare, and contrast ionic, covalent, and metallic bonding in solids; (d) State the structure-property relationships appertaining to melting temperature, modulus of elasticity and thermal expansion in reference to the potential energy curve between to atoms bonding chemically; (e) on what does the modulus of elasticity depend? (f) Why do solids (both brittle and ductile) exhibit very higher strength under compression than in tension?
