How do boiling points of halogens change
WebThe boiling points of halogens increase down the group due to the increasing strength of Van der Waals forces as the size and relative atomic mass of the atoms increase. This change manifests itself in a change in the phase of the elements from gas (F 2, Cl 2) to liquid (Br 2 ), to solid (I 2 ). WebWe can see a trend in the states of matter. Going down Group 17 from top to bottom the elements change from gaseous state to liquid to solid. The melting point of a substance reflects the amount of energy required to weaken the forces of attraction between molecules (intermolecular forces), the higher the melting point the stronger the forces of …
