Melting and boiling points: Sodium and magnesium chlorides are solids with high melting and boiling points because of the large amount of heat which is needed to break the strong ionic attractions.Electrical conductivity: Sodium and magnesium chlorides are ionic and so will undergo electrolysis when they are molten.

Answer 2

The other chlorides are simple covalent molecules. Melting and boiling points: Sodium and magnesium chlorides are solids with high melting and boiling points because of the large amount of heat which is needed to break the strong ionic attractions. The rest are liquids or low melting point solids.
