Question

Which properties make a metal a good material to use for electrical wires?

malleability and reactivity
conductivity and ductility
ductility and malleability
reactivity and conductivity

Answer 1

The properties that make a metal a good material to use for electrical wires are **conductivity and ductility**.

- **Conductivity** refers to the metal's ability to conduct electricity effectively, which is essential for wire applications.
- **Ductility** is the ability of the metal to be stretched into wires without breaking, allowing for the creation of long and thin wire shapes.

Therefore, the correct answer is **conductivity and ductility**.
