chemical formula for pyrite

Object of the Month

Pyrite has the chemical formula FeS2, meaning it is made up of one iron molecule, Fe, and two sulphur molecules, S. These then combine to form the cubic structure. This is a single pyrite crystal which you can see forms a perfect cube. A cube is not the only crystal shape that pyrite can form, however, and it can form many other crystal shapes ...
