Answer:
The correct answers to then question are
A and B
Explanation:
As highlighted, the atoms of the two isotopes are chemically identical and they have similar characteristics due to the presence of equal number of protons and electrons (92 each). Therefore factors influenced by the chemistry of the atoms of the isotopes such as the distance between atoms and the stiffness of the inter-atomic spring is identical for both and
An analogy of the spring constant and the inter-atomic distance is to consider the atoms of the metal to be interconnected by elastic material and as such the stiffness of the elastic material and the inter-atomic distance are determined by surface factors occurring on the surface
