Copper is a good conductor of electricity because it has free electrons. The free electrons in copper atoms align in one direction when an electrical potential is applied. Then they cross over to the positive terminal from the negative one. The electrons conduct electricity because they move while...

A useful property of copper is its ductility, or ability to be stretched. Copper can be pulled and twisted, yet it will not break. This makes it ideal for use as wire. Copper is a malleable metal, meaning it can easily be shaped and manipulated. As such, it is somewhat soft. Another...
