Can you identify this metal?

Last week’s curiosity was a piece of sulphur. Sulphur gas escapes from the volcanoes vent then it does something unusual as it cools. It does not turn into a liquid in a process called condensation like most gases. It turns straight into a solid in a process called sublimation.

This week, Can you identify the metal on the left? It has formed naturally in the rocks. There are a few metals that do this and they are called native metals but which one is this? Usually metals join with other elements to form a variety of minerals. A mineral of this metal is on the right. Here the metal is joined with carbon, oxygen and hydrogen to make a mineral called malachite.
