WebJan 30, 2024 · All crystal lattices are built of repeating unit cells. In a unit cell, an atom's coordination number is the number of atoms it is touching. The hexagonal closest packed (hcp) has a coordination number of 12 and contains 6 atoms per unit cell. The face-centered cubic (fcc) has a coordination number of 12 and contains 4 atoms per unit cell. WebQusongite is an extremely rare mineral with the simple formula WC, which shows the mineral to be a naturally occurring tungsten carbide. It was found in Luobusa ophiolite, China.
