Primitive cubic grating
Primitive cubic (and) simple cubic (sc)) is the name for a type of grating / ball stack where all grating points are on the cube vertices. The primitive cubic grating is one of fourteen Brava rattles. A primitive grating has a total of one grating point, which consists of 8 vertices each falling within 1/8 in the grating.
A primitive cubic crystal lattice One atom or ion per laneWhen a trellis repeats in the same position, in three independent directions (so that a very large grid is formed of bars next to each other), and an atom or ion is added at each lane point, the result is called a primitive cubic crystal lattice . The atoms or ions are then arranged in the same way as shown in the picture with the primitive cubic grating.
The element of polonium from the periodic table has a primitive cubic crystal grid. Multiple atoms or ions per lane
Multiple atoms or ions can also be filled at each lane point. Cesium chloride is an example of this. There is a cesium ion on each lattice point, and a chloride ion is at a distance of (1 / 2.1 / 2.1 / 2) of each cesium ion. The combination of two or more ions or atoms, which must be filled together at each trellion point, is also called a structural unit. In this case, the structural unit therefore consists of two ions; a cesium ion and a chloride ion. Other substances having this structure are, for example, cesium bromide and cesium iodide. Also see
