What is a notable feature of copper?

Copper is well-known for its excellent electrical conductivity, which is one of its most notable features. This property makes copper an ideal material for electrical wiring and components in various applications, ranging from household electrical systems to electronic devices. The high conductivity of copper is due to its atomic structure, which allows electrons to move freely, facilitating the flow of electric current.

In contrast to the other options, copper is quite malleable, allowing it to be shaped into various forms without breaking, and it is not dry and brittle; rather, it exhibits ductility. While copper may not be the most expensive metal, it generally has a moderate cost compared to other metals, which makes it accessible for many applications. The combination of its conductivity, malleability, and durability further contributes to its widespread use in various industries.
