Simple cubic coordination number, a concept fundamental to crystallography, is defined as the number of nearest neighbors surrounding an atom or ion in a simple cubic crystal structure. This structure is characterized by its regular arrangement of lattice points, forming a three-dimensional cube. Each atom or ion in a simple cubic lattice has six nearest neighbors, located at the corners of the cube and oriented along its edges. The coordination number in this structure is directly related to the packing efficiency, which is a measure of how closely the atoms or ions are packed together. The simple cubic coordination number has applications in materials science, chemistry, and physics, informing our understanding of crystal formation, the properties of materials, and the behavior of atoms and ions within these structures.
The Simple Cubic Coordination Number Explained
The coordination number in a crystal structure refers to the number of nearest neighbors that surround a given atom, ion, or molecule. In a simple cubic (SC) structure, each particle is surrounded by six other particles, which are located at the corners of a cube. This arrangement is also known as a cubic close-packed (CCP) structure.
The coordination number for a simple cubic structure can be determined by counting the number of nearest neighbors that surround a given particle. In the case of a simple cubic structure, there are six nearest neighbors that are located at the corners of a cube. These six nearest neighbors are all equidistant from the central particle.
The coordination number for a simple cubic structure can also be determined by using the following formula:
Coordination number = 8 – 2 * n
where n is the number of dimensions in the crystal structure. In the case of a simple cubic structure, n = 3, so the coordination number is 8 – 2 * 3 = 2.
The following table summarizes the coordination number for a simple cubic structure:
| Coordination Number | Crystal Structure |
|---|---|
| 6 | Simple Cubic (SC) |
The coordination number for a simple cubic structure is important because it determines the packing efficiency of the crystal structure. The packing efficiency is a measure of how efficiently the particles are packed together in the crystal structure. The higher the coordination number, the more efficiently the particles are packed together. In the case of a simple cubic structure, the packing efficiency is 52.4%.
