All ionic compounds that dissolve behave this way. Properties of Ionic Compounds DRAFT. Added 9/27/2016 4:43:28 AM If the strength of the attraction between the ions is much greater than the strength exerted by the slight charges of the water molecule, the ions remain bonded in water. The "O" atom has a partial negative charge, and the "H" atoms have a partial positive charge. The two classes of molecular compounds that do this are ____.
