The energy per ion in an ionic crystal can be modeled by . For a crystalline sample, the cohesive energy, defined as the absolute value of the total position-dependent interaction energy, per ion is 9.1 eV, the lattice constant is 1.7 nm, and the exponent is determined to be 7. What is the bulk modulus of this crystal?

Answer:

Interaction energy=9.1 eV

lattice constant=a=1.7 nm

We need figure out bulk modulus

Bulk modulus=9.1*1.7

Bulk modulus=15.47
