Which of the following best explains the polarity of water (H2O)? A. Electrons are more attracted to the oxygen atom, so there is a partial negative charge on the oxygen atom. B. Since the oxygen atom has more electrons than the hydrogen atoms, it is negatively charged. C. Since there are two positive hydrogen atoms and only one negative oxygen atom, the water molecule is positively charged. D. Protons are more attracted to the hydrogen atoms, so the hydrogen atoms become positively charged.
