I would like to understand when the water is boiled only pure vapor is produced and ions do not exist with vapor. Why?
Can't the ions stick to water vapor?
Are Na+ and Cl- have boiling points? Why do they not evaporate?

The ionic bond between sodium and chlorine ions is way stronger than the dipole-dipole interaction between water molecules. As a result, sodium chloride has much higher melting and boiling point than the boiling point of water.
So, sodium chloride does not vaporize at 100 degree centigrade under normal pressure.
