Within a water molecule is covalent bonds. between water molecules are hydrogen bonds.
When two water molecules get close together, the polar forces work to draw the molecules together. The oxygen atom of one water molecule will bond with several hydrogen atoms of other water molecules. These bonds are called hydrogen bonds. Hydrogen bonds are not as strong as covalent bonds, but they are strong enough to bind water molecules together and give water its unique characteristics.
