Main Question or Discussion Point
Hume–Rothery rules seem to be moderately satisfied for nickel to readily dissolve in silver. Silver has a radius of 144, valence of 1 and an electronegativity of 1.93. Nickel has a radius of 124, valence of 2 and an electronegativity of 1.91. Both elements have a fcc crystal structure. I read that nickel and silver are poorly soluble in liquid phase. Is this information incorrect?
