What is the structure of a water molecule?

H2o Atom

A water molecule consists of two hydrogen atoms and one oxygen atom.The three atoms make an angle; the H-O-H angle is approximately104.5 degrees. The center of each hydrogen atom isapproximately 0.0957 nm from the center of the oxygen atom.The structure of a single water molecule is shown below:

Because oxygen is more electronegative than hydrogen (in otherwords, electrons tend to be in the neighborhood of the oxygen),the hydrogen atoms end up with a partial positive charge andthe oxygen atom with a partial negative charge.This separation of charge produces a net dipole moment on themolecule; for the isolated water molecule this dipolemoment is approximately 1.85 Debye units.

This molecular structure leads tohydrogen bonding, which is a stabilized structurein which a hydrogen atom is in a line between the oxygenatom on its own molecule and the oxygen on another molecule.This picture shows a hydrogen-bonded structure betweentwo water molecules:

These hydrogen bonds, with their extra attractive energy,are the cause of many of the unusual properties of water,including its large heat of vaporization and itsexpansion upon freezing.
