Effects of bonds/potential energy on properties

[vasdueva]

The type and potential energy of interatomic bonds in solids have a direct effect on
which of the following properties? (That is, which can be determined based on
bonding information alone?)
a. Melting temperature-yes
b. Yield strength-no
c. Elastic modulus-yes
d. Fracture toughness-no
e. Diffusion coefficient-no
f. Ductility-yes
g. Coefficient of thermal expansion-yesI know bond type and potential energy has a direct impact on the melting temperature,thermal expansion coefficient, elastic modulus and ductility.

Bond type/potential energy doesn't effect the diffusion coefficient(only activation energy)

As far as the yield strength and fracture toughness goes, I'm going to guess they
can't be ascertained by only bond info, just intuition.

Does this seem correct?

Yes, your response is correct. The type and potential energy of interatomic bonds can only provide information about the melting temperature, elastic modulus, thermal expansion coefficient, and ductility. The yield strength and fracture toughness depend on other factors such as crystal structure and defects, and cannot be determined solely based on bonding information. The diffusion coefficient is also affected by factors such as temperature and pressure, and cannot be determined solely based on bond information.

Yes, your response is correct. The type and potential energy of interatomic bonds in solids can directly impact the melting temperature, thermal expansion coefficient, elastic modulus, and ductility. However, they do not have a direct effect on the yield strength, fracture toughness, and diffusion coefficient, which also depend on other factors such as crystal structure, defects, and external forces.
