In addition to mass, we can also measure how big a molecule is. A water molecule is about 0.27 of a nanometer across. DNA is about 2 nanometers across and can stretch out to meters in length. Amazing, when you think about that length of DNA being stuffed inside a cell. But that is because it is so thin, about 1/1,000,000,000 as thick as it is long.
The water molecule, as a whole, has 10 protons and 10 electrons, so it is neutral. In a water molecule, the oxygen atom and hydrogen atoms share electrons in covalent bonds, but the sharing is not equal. In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
