Coordination number of Na in NaCl is _
Correct answer: B. 6
- A. 4
- B. 6
- C. 8
- D. 3
Explanation
In NaCl (sodium chloride), each Na ion is surrounded by six chloride (Cl) ions, and each Cl ion is surrounded by six sodium (Na) ions. This gives Na an octahedral coordination geometry and a coordination number of 6. In other words, each Na ion in NaCl is directly bonded to six chloride ions and is therefore said to have a coordination number of 6.

About Shape of Ionic Crystals
Ionic crystal shape depends on the regular arrangement of oppositely charged ions in a three-dimensional lattice. The topic covers coordination number, radius ratios, lattice geometry and structures such as sodium chloride, caesium chloride and zinc sulfide, which should not be confused with the molecular shapes predicted by VSEPR theory.
