Elements get heavier as the periodic table progresses down the line.
In an aqueous solution that has not reached the saturation, the ions do not bond to create mineral crystals the motion of the ions that are dissolved would keep them from bonding. The ions creates temporary bonds to the partial charge present in the water molecules which will not allow for the ions to form a compound.
