Within a water molecule is covalent bonds. between water molecules are hydrogen bonds.
The weak bonds between water molecules are called 'hydrogen' bonds. Hydrogen bonding is due to the fact that most of the time the electrons in a water molecule are around the oxygen atom - thus conferring a negative charge on the oxygen part of the molecule and as a consequence a positive charge on the hydrogens.
