WebAug 14, 2024 · Each corner atom is shared with eight adjacent unit cells and so a single unit cell can claim only 1/8 of each of the eight corner atoms. Similarly, each of the six atoms centered on a face is only half-owned by the cell. The grand total is then (8 × 1/8) + (6 × ½) = 4 atoms per unit cell. WebThe video describes defining selections, making a crystal packing figure, and defining colors for different chains of the molecule in a detailed manner.
WebThe packing efficiency is the fraction of the crystal (or unit cell) actually occupied by the atoms. It must always be less than 100% because it is impossible to pack spheres …
WebThe diagrammatic representation of three-dimensional arrangements of constituent particles in a crystal, in which each particle is depicted as a point in space is known as crystal lattice. In a crystal lattice, the atoms are very closely packed leaving very little space between them.
