For a substitutional alloy to form,the two metals combined must have similar ________.
A)ionization potential and electron affinity
B)number of valance electrons and electronegativity
C)reduction potential and size
D)atomic radii and chemical bonding properties
E)band gap and reactivity

Question

Quizplus · Accepted Answer

For a substitutional alloy to form, the two metals must have similar atomic radii and chemical bonding properties. This allows for the atoms of one metal to substitute for the atoms of the other metal in the crystal lattice. Option A is incorrect as ionization potential and electron affinity are not relevant to the formation of substitutional alloys. Option B is partially correct in that the metals should have a similar number of valence electrons, but electronegativity is not relevant. Option C is incorrect as reduction potential and size are not relevant to the formation of substitutional alloys. Option E is incorrect as band gap and reactivity are not relevant to the formation of substitutional alloys.
