How would you predict the properties of sodium chloride compare with those of its constituet elements?

Sodium is a metal. Chlorine is a non-metal.

Sodium chloride should be an ionic compound.

IThe physical properties of sodium chloride should be

•solid

•high melting and boiling points

•brittle

•poor conductor of electricity

•aqueous solutions should be good conductors of electricity

The physical properties of sodium are

•solid

•metallic lustre

•malleable and ductile

•good conductor of electricity

The physical properties of chlorine are

•pale green gas

•low melting and boiling points

•poor conductor of electricity
