Group 7 elements are commonly known as . They normally exist as of atoms.
They become reactive down the group – because the shell is further from the nucleus so it is to gain an electron.
They have higher melting and boiling points the group.
A more reactive halogen will a less reactive halogen.

( Simple distillation, Filtration, Crystallisation/evaporation, Fractional Distillation, Chromatography ) is a method for separating the ( solvent, solute, solution, solid ) from a ( solution, solute, solid, solvent ), leaving behind the ( solute, solvent, solution, solid ). This method works because the solvent has a much lower ( boiling point, melting point, crisis point, critical angle ) than the dissolved solute. Heating the solution allows the solvent to ( evaporate, condense, freeze, melt ), and then it passes through a condenser, where it is cooled and condensed into a separate container. The ( solute, solvent, solid, solution ) does not evaporate and so it stays behind.
