• Sodium chloride lattice has Cl ñ ions and Na + ions separately  organized in face-centered cubic arrays that penetrate each other.

Sodium chloride unit cell

• Each cation is surrounded by six anions and vice versa.

• The four Cl ñ [(8 x1 ¼ 8 )+(6 x 1 ¼ 2 ) = 4 Cl ñ ] and four Na + [(12 x 1 ¼ 4 ) + 1 in the center = 4 Na + ] give the 1/1 stoichiometric ratio of NaCl.
