Which of the following elements would typically have a high malleability?

Iron is the element that typically exhibits high malleability. Malleability is a property of metals that allows them to be hammered or pressed into thin sheets without breaking. This characteristic arises because metallic bonds enable atoms to slide past one another when a force is applied. Iron, being a metal, has a structure that accommodates this movement, allowing it to be easily shaped and formed without fracturing.

In contrast, carbon, sulfur, and oxygen are nonmetals with different bonding and structural properties. While carbon in certain allotropes, like graphite, can exhibit some degree of malleability, it is not a characteristic associated with carbon in its most common forms, such as diamond. Sulfur and oxygen are not malleable; they typically break or shatter under stress rather than deform, which is indicative of their non-metallic and brittle nature. Therefore, iron stands out as the element with high malleability among the choices given.
