I know that if you heat a molecular compound, e.g. water, it will eventually 
boil and the individual molecules will escape from the surface of the liquid.

What happens with an ionic compound, e.g. sodium chloride? Do individual Na+ 
and Cl- ions escape from the liquid? If that were the case, surely they would 
easily react with the air.

What would happen if the molten NaCl was boiled in a vacuum?
