Uranium and Springs: Same Interatomic Distance & Stiffness?

In summary, the behavior of atoms in two isotopes is similar due to the identical number of protons and nearly identical electron clouds. The interatomic distance and stiffness of the bond depend on the chemical properties of the atoms, not the nuclear mass. Therefore, the interatomic distance is the same for both isotopes, while the effective stiffness may be greater for U238 due to its larger mass. However, the effective stiffness is ultimately the same for both isotopes, as it is based on the interactions of the outer electrons which are the same for different isotopes of the same atom.

Homework Statement


Chemically, the atoms of these two isotopes behave in essentially identical ways, since the number of protons (92) is identical and the clouds of 92 electrons are nearly identical. The interatomic distance, and the effective "stiffness" of the interatomic bond, both depend on the chemical properties of the atoms. Therefore, which of the following statements are true?

The interatomic distance is the same for the two isotopes, because it depends on the size of the electron cloud, not the nuclear mass.

An atom with more mass in the nucleus is bigger, so the distance between neighboring atoms is larger.

The effective stiffness of the interatomic "spring" is greater for U238 because the mass is greater.

The effective stiffness of the interatomic "spring" is the same in the two isotopes, since this "spring" is a model for the interactions of the outer electrons, which are the same for different isotopes of the same atom.
