E) None of the above is true.

Question

Quizplus · Accepted Answer

One of the key requirements for the formation of a substitutional alloy is that the metals involved should have similar radii. This is because the process involves replacing some of the host metal atoms with atoms of a different metal, and if the radii are substantially different, it can lead to defects in the crystal structure.
