Crystal structure of elements
Webimpossible if the most stable elements were not regular crystal lattices. The N-body problem is reduced to manageable proportions by the ex-istence of translational symmetry. This means that there exist a set of basis vectors (a,b,c) such that the atomic structure remains invari-ant under translations through any vector which is the sum of integral

WebThe three most common basic crystal patterns are: bcc. In a bcc (BCC) arrangement of atoms, the unit cell consists of eight atoms at the … WebA possible crystal structure of Carbon is hexagonal structure. In metals, and in many other solids, the atoms are arranged in regular arrays called crystals. A crystal lattice is a repeating pattern of mathematical points that extends throughout space. The forces of chemical bonding causes this repetition.
For elements that are solid at standard temperature and pressure the table gives the crystalline structure of the most thermodynamically stable form(s) in those conditions. In all other cases the structure given is for the element at its melting point (H, He, N, O, F, Ne, Cl, Ar, Kr, Xe, and Rn are gases at STP; Br, Hg, … See more Close packed metal structures Many metals adopt close packed structures i.e. hexagonal close packed and face-centred cubic structures (cubic close packed).
