Question

Identify the metals by its sequential order from its maximum to minimum ductility?
(A) Lead
(B) Tin
(C) Zinc
(D) Aluminum
(E) Copper
Choose the correct answer from the options given below:

• A. (E), (D), (C), (B), (A)
• B. (A), (B), (E), (D), (C)
• C. (D), (E), (A), (B), (C)
• D. (A), (B), (C), (D), (E)

Hint:

High ductility is often associated with good electrical conductivity. Metals used for wires (like copper and aluminum) are at the top of the ductility list, while soft, heavy metals (like lead) are at the bottom.

Answer 1

The Correct Option is A

Step 1: Define ductility. Ductility is the ability of a material to be drawn into a thin wire.
Step 2: Order the given metals based on their ductility, from highest to lowest.

(E) Copper: Is highly ductile, a key reason for its use in electrical wiring.
(D) Aluminum: Also very ductile and used for wiring. Generally considered slightly less ductile than copper.
(C) Zinc: Has moderate ductility.
(B) Tin: Has low ductility.
(A) Lead: Is very soft but has very poor ductility; it cannot be easily drawn into a wire.

Step 3: Form the sequence. The correct order from maximum to minimum ductility is Copper, Aluminum, Zinc, Tin, Lead. This corresponds to the sequence (E), (D), (C), (B), (A), which matches option (1).
