What lattice structure does NaCl have?

face centered cubic Bravais lattice
NaCl is a crystal structure with a face centered cubic Bravais lattice and two atoms in the basis.

How is NaCl fcc?

NaCl is a FCC unit cell which has four cations and four anions. This can be shown by counting the number of ions and multiplying them in relation to their position. In NaCl, each ion is surrounded by six ions of two opposite charges as expected on electrostatic grounds.

How many atoms are in NaCl unit cell?

4 atoms
Hence, there are 4 atoms present in each unit cell of a face centred cubic structure. Hence, Option C is the correct option. Note: NaCl has a cubic unit cell that can be represented as a face-centred cubic array of anions with an interpenetrating fcc cation lattice (or vice-versa).

What is the basis of NaCl structure?

Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit cell with ion locations indicated (a) and a space filling model (b) of ionic hard spheres.

What is the geometry of NaCl?

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.

What is coordination number of NaCl?

In NaCl crystal, each sodium ion is surrounded by 6 chloride ions and each chloride ion is surrounded by 6 sodium ions. So, the coordination number of NaCl as per definition will be 6:6.

What is the unit cell of NaCl?

cubic unit cell
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.

What is unit cell of NaCl?

General Notes. 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.

What is the lattice spacing of NaCl?

nglos324 – nacl. Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm.
