The diameter is about 0.29 nm. The atomic diameter can be determined from interpolation of the effective ionic radii of the isoelectronic ions (from crystal data) of O2- (2.80 Å), OH- (2.74 Å) and H3O+ (2.76 Å). Coincidentally, this diameter is similar to the length of a hydrogen bond. The water molecule (bond length 0.96 Å) is smaller than ammonia (bond length 1.01 Å) or methane (bond length 1.09 Å), with only H2 (bond length 0.74 Å) and HF (bond length 0.92 Å) being smaller molecules. Answer from Esteban Broitman, September 7 2008.
Going by the ol' rule of the nano-thumb, there are six water molecules end to end in a nanometer, which is one billionth of a meter. An angstrom is 1/10 of a nanometer. A picometer is 1/1000th of a nanometer. So a single water molecule would be:
1/6th of one billionth of a meter
1.67 angstroms
167 picometers (167 trillionths of a meter)
Or 167 x 10 -12 meters (that's 167 times 10 to the minus 12 meters)
140 Picometer lengthwise
one picometer equals one trillionth (1/1,000,000,000,000) of a metre.
The height of an adsorbed monolayer of water, about 2.5 Angstroms or 2.5*10^-10 meters, is the width of a water molecule.
The molecular diameter of water is 2,75 angstroms.
About 3x10-10m
0.278 nm

Unequal sharing of electrons in a water molecule causes the molecule to be polar.
water is a polar, covalent molecule. it doesn't have an unsharing molecule. its also has to do with the 8 properties of water.
molecule
There are two covalent bonds present in a water molecule.
A polar molecule is a molecule with slight opposite charges. Water is a polar molecule which means that each water molecule is attracted to other water molecules which accounts for waters surface tension or cohesion.

The molecule of water has the chemical formula H2O.
Because of its shape, water is a polar molecule.
No, water is not the only molecule that is polar.
It makes the molecule polar
