Sodium Chloride (NaCl) Crystal – PhysicsOpenLab
2018年1月22日 · For a perfect crystal the lattice gives the reciprocal lattice, which determines the positions (angles) of diffracted beams, and the basis gives the structure factor which determines the amplitude and phase of the diffracted beams for the (hkl) crystal plane.

7.2.2: Lattice Structures in Crystalline Solids
When an ionic compound is composed of a 1:1 ratio of cations and anions that differ significantly in size, it typically crystallizes with an FCC unit cell, like that shown in Figure \(\PageIndex{15}\). Sodium chloride, NaCl, is an example of this, with Na + and Cl − having radii of 102 pm and 181 pm, respectively. We can think of this as ...
Structure World: NaCl
2020年12月2日 · NaCl has a cubic unit cell. It is best thought of as a face-centered cubic array of anions with an interpenetrating fcc cation lattice (or vice-versa). The cell looks the same whether you start with anions or cations on the corners. Each ion is 6-coordinate and has a local octahedral geometry.
separate the ions is called the lattice energy. The figures opposite show part of the structure of NaCl and the cubic unit cell which generates the whole lattice when repeated infinitely in all directions. The distance between the ions is determined by the balance of the attractive force between cation and
Describe the ionic crystal structure of NaCl. - CK-12 Foundation
The ionic crystal structure of Sodium Chloride (NaCl) is known as the face-centered cubic (FCC) lattice structure or cubic close-packed structure. In this structure, each ion is surrounded by six ions of the opposite charge, forming an octahedral arrangement.
