Understand the concept of malleability: Malleability is a physical property of metals that allows them to be hammered or rolled into thin sheets without breaking.
Identify the types of elements given: Oxygen (O), Sulfur (S), and Phosphorus (P) are nonmetals, while Gold (Au) is a metal.
Recall that metals are generally malleable due to their metallic bonding, which allows atoms to slide past each other without breaking the structure.
Recognize that nonmetals like Oxygen, Sulfur, and Phosphorus are typically brittle or gaseous solids and do not exhibit malleability.
Conclude that among the given elements, Gold (Au), being a metal, is malleable at standard temperature and pressure (STP).
