The correct answer is: D. Oxygen has more protons than hydrogen and water's shared electrons are drawn to it
In water (H2O), each hydrogen atom has one positively-charged proton surrounded by a 'cloud' of one negatively-charged electron. The oxygen atom has a nucleus with eight positively-charged protons, eight uncharged neutrons and eight negatively-charged electrons. Two electron pairs of oxygen are forming covalent bonds with hydrogen, while other two pairs are lone pairs. The eight positive charges in the oxygen attract electrons strongly and this leaves the hydrogen atoms partially positively charged, and the oxygen atom partially negatively charged.
