Low resistance, free electrons, efficient... See more below.

Explanation:

Metals conduct electricity well because they have a very low resistance that decreases the difficulty that there is for the current to pass through them (around 0.0001 ohms). They also have a lot of free electrons in them which provided the electricity to move more efficiently, consequently, copper (a metal $C u$) is used to make wires.

I would also recommend that you have a look on BBC Bitesize as they provide good explanations and constructive videos!

Hope this helped you out just that extra but :)!
