Each sphere in a cF lattice has coordination number 12. Coordination number is the number of nearest neighbours of a central atom in the structure. The face-centered cubic system is closely related to the hexagonal close packed (hcp) system, where two systems differ only in the relative placements of their hexagonal layers. The plane of a face ...

May i know how to count the coordination number of fcc? i know coordination number is count by the number in contact. i can understand the coordination number of bcc which is 8 , becoz that is 8 number in contact . but why fcc is 12 , not 13? i counted it as 13 if we take one face atom as 'reference ...

en.wikipedia.org/wiki/Coordination_number

In chemistry, crystallography, and materials science, the coordination number, also called ligancy, of a central atom in a molecule or crystal is the number of atoms, molecules or ions bonded to it. The ion/molecule/atom surrounding the central ion/molecule/atom is called a ligand.This number is determined somewhat differently for molecules than for crystals.

The coordination number of a face-centered cubic, or FCC, is 12. This represents the number of other atoms that an atom touches within the crystal lattice structure. Atoms generally self-organize into a crystalline lattice.

Coordination Number Besides the simple cubic (sc) and the face centered cubic (fcc) lattices there is another cubic Bravais lattice called b ody c entered c ubic ( bcc ) lattice. Unlike the simple cubic lattice it has an additional lattice point located in the center of the cube.

This Site Might Help You. RE: How is the coordination number of a face centered cubic 12? Do we count the center atoms only? So is it because of 4 closest atoms on each plane.
