What do graphite, galena, magnetite, and pyrite have in common?

Graphite

Graphite is a form of carbon that is made up of layers of carbon atoms arranged in a hexagonal lattice.

Galena

Galena is a lead sulfide mineral that has a metallic luster.

Magnetite

Magnetite is an iron oxide mineral that is highly magnetic.

Pyrite

Pyrite is an iron sulfide mineral that has a brassy yellow color and metallic luster.

In terms of their chemical composition, graphite, galena, magnetite, and pyrite all contain elements that have metallic properties. These elements are important in various industrial and technological applications, such as electrical conductivity, magnetism, and corrosion resistance.
