Using the information we have learned about binding energy in atomic bonding, determine - using calculations - the relative stiffness of the materials (i.e. the ratio of stiffness of A to B) Recall that stiffness is related to the material property: "modulus of elasticity." Show all work, and identify the key features of the atomic bonds (equilibrium spacing, binding energy, and stiffness) and plot the binding energy and interatomic forces for both materials (label the plots well so it is apparent which is which). The interatomic energy (IAE) for both materials are represented by the equations below, where r is the radius. Also: Answer the following: a) which material has the highest melting point? b) which material has a larger coefficient of thermal expansion? c) Which material likely has the lowest density? d) Which material has the strongest bond? -2.2 x 10-1 J nm 10-261 nm IAEmateriala(r) : r9 12 0.18 пту 0.33 пт IAEmaterialB (r) = 4 * 2.2 x 10-2 J
