How do the physical and chemical properties of halogens change with a change in their relative atomic masses?

The main physical properties of halogens are:
1) With an increase in the atomic weight of a halogen, its color acquires a brighter shade
2) The temperature rises when the radii of the halogen atoms increase
3) Halogens, which are normally found in nature, are oxidizing agents.
The main chemical properties of halogens are:
1) The activity of halogens changes downward with increasing atomic mass
2) The solubility of halides increases with heating
3) Halogen exhibits the highest oxidizing properties when it has the lowest atomic mass.
