Final answer:
Metals with different crystal structures typically do not form a substitutional solid solution due to differences in size and arrangement of atoms. More information is needed to determine if a substitutional solid solution is possible in a specific case.
Step-by-step explanation:
It is generally not likely for metals with different crystal structures to form a substitutional solid solution because the size and arrangement of atoms in the lattice are crucial for substitution to occur without altering the crystal structure significantly.
For a substitutional solid solution to form, it is typically necessary that the two metals have similar atomic radii, crystal structures, and electronegativities. However, there are exceptions, and under certain conditions, metals with different crystal structures might form some degree of substitutional solid solution, especially if the differences in atomic size are within roughly 15%
Answering the question, there isn't enough information given to definitively determine if different crystal structures would prevent the formation of a substitutional solid solution entirely (D. Not enough information given to determine the answer).
