Boiling point trend down the group
WebAs you go down group 17 from top to bottom, the melting point of the elements increases and the boiling point increases. We can use the melting point and boiling point to determine the state of each element at standard temperature and pressure (25°C, 100 kPa). If element is a: gas: boiling point < 25°C liquid: melting point < 25°C < boiling point WebWell, melting and boiling points increase as you move down group 7 in the periodic table. The large increase in the number of electrons is therefore more important than the reduced permanent dipole strength. You can see this in the table below.
