Atomic Radius: The atomic radius increases down the group. As the no. of shell increases which means more electrons are present and the distance between the nucleus and outer electron increases.
Electronegativity: There is a decrease in electronegativity down the group since the distance between nucleus and the bonding electron increases and electrons are attracted less strongly by the nucleus.
Volatility; The volatility decreases and this is because down the group the no. of electron increases causing more temporary dipoles to be set therefore increasing the strength of LDF forces which means increased boiling and melting points and they become less volatile.
Color : The color gets darker going down the group starting with fluorine as yellow and with astatine as black.
Solubility; The solubility of the halogens in water decreases as they cannot overcome and form bonds with the strong hydrogen present in water since they are non polar and water is polar .However, in inorganic solvents due the presence of non polar molecules ,they can form bonds and are therefore soluble.

They all posses 7 electrons in their valence shells and the halogens have an unpleasant odor and maybe toxic.

This is because melting and boiling point increase down the group as there are more number of electrons down the group so there are more London dispersion forces. The lower the boiling point, the more volatile the halogen.

Colour: Colour of halogens at r.t.p. becomes darker down the group.

solubility:
halogens are less soluble in water because they cannot form bonds to overcome the strongly bonded molecule of water.

halogens are more soluble in organic solvents (hexane) because they both are non-polar molecules.

The halogens are insoluble in polar solvents such as H20 and soluble in organic solvents such as ethanol 
The reactivity decreases. 
The electronegativity decreases down the group, the atomic and ionic radius increases down the group. The colours get more darker down the group.

Volatility: Decreases down the group ( as physical state goes from gas to liquid to solid at rtp). This is due to the size of the atom increasing, meaning there are more electronic shells which leads to a large number of dispersion forces, increasing the b.p.

COLOR- turns darker down the group.
BOILING POINT-  increases down the group as increased size makes the induced dipole-dipole interactions rise, hence more energy required to separate the molecules
ELECTRONEGATIVITY- decreases down the group  as increasing number of shells  cause more shielding and less pull on electrons, the increasing atomic radius leads to drop in attraction as distances increases.
OXIDISING POWER- gets weaker down the group as the nucleuses attraction for the incoming electron which is affected by the rising nuclear charge which should attract the electrons more , but is interrupted by the increased shielding and atomic radius.
SOLUBILITY IN WATER- decreases as they are non polar and unable to form bonds with hydrogen 
SOLUBILITY IN ORGANIC SOLVENTS- increases as organic solvents and halogens are both non polar so molecules are attracted to eachother by van der waals forces.

2.Atomic size increases down the group because the extra shells get filled
3.Melting and boiling points also increase down the group as the strength of Van der Waals forces increases.
4.Halogens change in state from gas to liquid to solid as you go down the group.
5.Halogens act as oxidising agents and become less oxidising down the group.
6.Halogens are more soluble in organic solvents (like hexane or cyclohexane) than in water because both halogens as well as hexane are non-polar and so they are attracted by Van der Waals dispersion forces.
7. Volatility decreases down the group as atomic size increases so number of electrons increase.

-Boiling points increase down the group
-Melting points increase down the group
-Volatility decreases down the group

This is because the atomic number of each halogen decreases down the group, so more electrons are present. And therefore the VanderWaal's forces between diatomic molecules increase and more energy is required to overcome the attraction.
