Agric. Water is a polar molecule because the electronegativity of oxygen is higher than that of hydrogen, meaning that the electron density is shifted towards the oxygen atom in the molecule. When molecules are polar this means that one section of the molecule has a slightly positive charge and another section has a slightly negative charge. The atoms attached to the atom arent all the same.
