4 Copper Copper 29 64.546 Cu Copper, like many of the transition metals, does not form ions the way we are used to seeing. A common ion for copper is Cu2+

5 Copper Copper 29 64.546 Cu Likely the first metal used by humans thousands of years ago. It is relatively easy to mine and bend so it was one of our first metal tools. Ancient uses were weapons and jewelry.

6 Copper Copper 29 64.546 Cu Copper is a useful tool, but it is much stronger as an alloy when it is bonded with zinc and other elements. Two very popular alloys are bronze and brass Bronze weapons, jewelry, statues replaced copper ones and were such a popular alloy the Bronze Age is named after them. Brass is popular for instruments and other soft uses. The discovery of copper dates from prehistoric times. There are reports of copper beads dating back to 9000BC found in Iraq. Methods for refining copper from its ores were discovered around 5000BC and a 1000 or so years later it was being used in pottery in North Africa.

7 Copper Copper 29 64.546 Cu Today copper is used for its ability to conduct electricity very well. Mines throughout the world extract this metal for many uses. Most of our wiring on the planet is made from copper as well as many computer parts. The discovery of copper dates from prehistoric times. There are reports of copper beads dating back to 9000BC found in Iraq. Methods for refining copper from its ores were discovered around 5000BC and a 1000 or so years later it was being used in pottery in North Africa.
