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 a material's capacity to be stretched into a wire.
Step 2: Rank the provided metals by ductility, from greatest to least.

(E) Copper: Exhibits high ductility, making it suitable for electrical wiring.
(D) Aluminum: Also highly ductile and used in wiring, though slightly less ductile than copper.
(C) Zinc: Possesses moderate ductility.
(B) Tin: Displays low ductility.
(A) Lead: Is very soft but poorly ductile; it's difficult to draw into a wire.

Step 3: Establish the sequence. The correct order from most to least ductile is Copper, Aluminum, Zinc, Tin, Lead, corresponding to (E), (D), (C), (B), (A), matching option (1).
