MCQ
Sodium chloride crystal has a $.....$ shape:
- ✓Definite
- BRegular
- CIrregular
- DNone of these
✓
Answer
Correct option: A.
Definite
In $\text{NaCl}$ crystal, there exists strong ionic bonding between $\mathrm{Na}^{+}$ and $\mathrm{Cl}^{-}$ions. Because of stronger forces of attraction between $\mathrm{Na}^{+}$ and $\mathrm{Cl}^{-}$, they remain fixed at their positions, thus, arranging in a definite pattern to give a definite shape.
