Platinum atoms are arranged in closely packed hexagonal layers. A top view of this hexagonal structure is shown in this scanning tunneling microscope image.
Platinum has applications in automotive engineering, chemical processing, jewelry, electronics, and wires and electrical contacts for use in corrosive or high-voltage environments. Platinum is also a component in magnetic coatings for high-density hard disc drives and new varieties of optical storage systems.

The size of a platinum atom is around 0.3 nm.
