Below, atomic radius, crystal structure, electro negativity, and the most common valence are tabulated, for several elements; for those that are nonmetals, only atomic radii are indicated.

Which of these elements would you expect to form the following with copper?

(a) A substitutional solid solution having complete solubility

(b) A substitutional solid solution of incomplete solubility

(c) An interstitial solidsolution
