Question

why sodium chloride has crystalline structure​

Answer 1

Answer:

Because in crystalline structure of NaClNaCl 6 electrons of Na+NaX+ ion are surrounded by 6 electrons of Cl−ClX− ion and 6 electrons of Cl−ClX− ion are surrounded by 6 electrons of Na+NaX+. That's how NaClNaCl maintains its crystalline structure.

Answer 2

Answer:

hi

here is your answer

This equivalent to saying that sodium ions occupy all the octahedral sites. ... To accommodate large sodium ions, the arrangement of chloride ions has to slightly open up. It is obvious from the diagram that each chloride ion is surrounded by six sodium ions which are disposed towards the corners of a regular octahedron.
