9.2 Uses of metals question 1

[Maximum number: 1]

Iron is a transition element. Potassium is a Group I element.

Transition elements and Group I elements have some similar physical properties.

They can both:
- be hammered into a shape
- conduct electricity
- be stretched into wires.

Suggest why copper, rather than other transition elements, is used for wires which conduct electricity.
