Water molecules comprise one oxygen atom covalently joined to two hydrogen atoms. H2O is a highly polarised molecule which leads to hydrogen bonding among the molecules. In the model above, the central oxygen atom (red) is pictured as a sphere drawn at the scale of its covalent radius just touching two hydrogen atoms (blue) drawn at the scale of their covalent radii. The transparent spheres represent the "surfaces" of each molecule and are created from the van der Waals radii of the constituent atoms.
