A single molecule of water consists of three atoms. H2O is built from a single atom of oxygen that is single-bonded with two atoms of hydrogen.
Water is a polar molecule composed of two hydrogens and one oxygen. The oxygen is slightly negative, while the hydrogens are slightly positive. The hydrogens form hydrogen bonds with the oxygen of adjacent molecules. Then, those molecules form more bonds with other adjacent water molecules.
