Yes. Compare the electronegativities of oxygen and hydrogen. Whichever is more electronegative will have more of a claim on the electrons, drawing them toward itself, and becoming slightly negative. So the oxygen becomes negative and the hydrogen positive. Polar liquids like water will dissolve anything that is made of positive and negative ions - like salt- and mix easily with other polar liquids - like ethanol - but not with non-polar liquids like oil. Water is a liquid because of the difference in electronegativity of the oxygen and hydrogen; the oxygen of one molecule will attract the hydrogen of the neighbouring molecule and so on. If this didn't happen there wouldn't be any liquid water on our planet and life would not have evolved the way it has. So all of life depends on the difference in electronegativity between two little atoms.
