Correct Answer:
Option A —
Gold
Gold is the most malleable and ductile of all known metals. To give you an idea of its extreme properties, a single gram of gold can be beaten into a sheet covering nearly one square meter.Understanding Malleability
Malleability is a physical property of metals that defines their ability to be hammered, pressed, or rolled into thin sheets without breaking or cracking.
Atomic Structure: Gold's atoms are arranged in a "face-centered cubic" lattice. The layers of atoms can slide over each other relatively easily when pressure is applied, allowing the metal to change shape rather than shatter.
Corrosion Resistance: Unlike many other metals, gold does not oxidize or tarnish, which helps it maintain its structural integrity even when beaten into extremely thin "gold leaf" (which can be so thin it becomes translucent).
Industrial and Artistic Use: Because of its malleability, gold is used extensively in jewelry, dentistry, and even high-end electronics where delicate, thin connections are required.
