Oxygen, which is plentiful in the atmosphere, requires two electrons to remain stable. Two oxygen molecules have four electrons, and two of them are unpaired. As a result, the metal reacts with oxygen to formtungsten trioxide, which is brown in color. This chemical reaction occurs even when tungsten is pure. Tungsten carbide is a type of metal-like substance. It is made up of tungsten, carbon, and cobalt which is the binder.
