Molecular structure of water. Illustration of the structural organization of the molecules of H2O. Each water molecule has a tetrahedral structure with the oxygen atom in the centre. Two hydrogen atoms (with a positive charge density) are in two of the four corners, and two non-bonding orbitals occupied by two electrons (with a negative charge density). This leads to the formation of transient hydrogen bonds between water molecules, forming a stable structure which causes liquid water to be more compact than its solid form (ice). The bonding repeats such that every water molecule is hydrogen-bonded with up to four other molecules.
