Question

Sodium chloride crystal has a ________ shape.

• A. Definite
• B. Regular
• C. Irregular
• D. None of these

Answer 1

The correct option is A Definite

In $NaCl$ crystal, there exists strong ionic bonding between $N{a}^{+}$ and $C{l}^{-}$ ions. Because of stronger forces of attraction between $N{a}^{+}$ and $C{l}^{-}$, they remain fixed at their positions, thus, arranging in a definite pattern to give a definite shape.
