Which property of metals allows them to be reshaped without breaking?

Malleability is the property of metals that allows them to be reshaped without breaking. This characteristic enables metals to be hammered or rolled into thin sheets without fracturing. The atomic structure of metals consists of layers of atoms that can slide over one another when force is applied, which is why they can be reshaped easily.

When metals are manipulated, such as during metalworking processes, the metallic bonds allow for the rearrangement of atoms while maintaining the integrity of the material. This property is particularly useful in various industrial applications, such as in the manufacturing of aluminum foil or the creation of metal components that require specific shapes.

Ductility is related but specifically refers to a metal's ability to be drawn into wires, showcasing the broader category of malleability. Conductivity pertains to the ability of metals to conduct electricity and heat and does not relate to their ability to be reshaped. Brittleness, on the other hand, refers to the tendency of a material to break or shatter without significant deformation, which is contrary to the concept of malleability.
