Chemistry periodic table group 7

Periodic table

Group 7

The melting and boiling points of the halogens increase as you go down the group This is due to increasing intermolecular forces as the atoms become larger, so more energy is required to overcome these forces

Reactivity of group 7 non-metals decreases as you go down the group

As you go down group 7, the number of shells of electrons increases, the same as with all other groups

However, halogen atoms form negative…
