Answer to Question #65172 in Physical Chemistry for babu

Question

explain important feature of crystal structure of sodium chloride

Answer 1

For crystal NaCl, 6 where the coordination number for the cation and anion of the unit cell will look different, not like most other crystals. The unit cell in NaCl has octahedral form. Elementarnoy NaCl cell corresponds to a face-centered cubic packing, and, for example, CsCl crystal cell - body-centered cubic packing. Names packages speak for themselves: in the face-centered is a particle at the center of each face of the cube, and have a body - a particle is located in the center of the cube.
Answer: face-centered cubic packing, octahedral form
