Why Iodine doesn't dissolve in water?

Iodine has a very low solubility in water because it is non-polar ... As a result, an I₂ molecule cannot form strong interactions with water molecules (no hydrogen bonds or permanent dipole-dipole interactions), whereas water molecules do form strong interactions with each other.

Iodine has a very low solubility in water because it is non-polar. Its an element from grp 7 in periodic table and grp7 elements mostly react with grp1 elements to form salt i guess ... well non polar means

When atoms bond together to form molecules, they share or give electrons. If the electrons are shared equally by the atoms, then there is no resulting charge, and the molecule is nonpolar. that s all ik
