Question

Addition of non-metals like B and C to the interstitial sites of a transition metal results the metal :

• A. of more ductability
• B. of less ductability
• C. Less malleable
• D. of more hardness

Answer 1

Answer: (B), (C), (D)

of less ductability
Less malleable
of more hardness

Addition of non-metals like B and C to the interstitial sites of a transition metal results in the more hardness so it will be less ductile and less malleable.
Hence options B,C & D are correct.
