Question

Which of the following terms means that metals can be rolled into thin sheets, as in aluminum foil, or beaten into complex shapes?

1) Malleability
2) Ductility
3) Conductivity
4) Corrosion

Answer 1

The property that allows metals to be rolled into thin sheets or shaped is called malleability. Therefore, the correct answer is option 1.

Step-by-step explanation:

Malleability is the property that enables metals to be rolled into thin sheets or crafted into intricate forms, exemplified by aluminum's transformation into flexible foil. Concurrently, ductility characterizes a metal's capacity to be drawn into slender wires. The remarkable ability of metals to conduct both heat and electricity results from the mobility of their free-flowing electrons. This attribute, coupled with the typical metallic lustre, imparts a shiny appearance. Metals, solid in nature, generally boast high density and melting points, stemming from their densely packed atomic structures.

Despite exceptions like mercury, which remains liquid at room temperature, the pervasive solidity of metals underscores their structural integrity. In essence, the collective properties of malleability, ductility, conductivity, lustre, solidity, and density define the diverse and essential characteristics inherent to metallic elements.
