The melting point of sodium chloride is ...

The melting point of sodium chloride is more than that of sodium. Justify.

Text Solution

Verified by Experts

Sodium chloride is an ionic solid in which the `Na^(+)` and `Cl^(-)` ions have strong coloumbic forces of attraction. But sodium is a metallic solid in which the attractive forces are comparatively weak. Therefore, melting point of solidum chloride is move than that of sodium.
