The type of bond that forms between two water molecules is hydrogen bonds.
Water (H₂O) molecules are polar, meaning they have a slight positive charge on one side (where the hydrogen atoms are) and a slight negative charge on the other side (where the oxygen atom is). This polarity allows water molecules to attract one another through hydrogen bonding, which is a relatively weak interaction compared to covalent or ionic bonds.
Covalent bonds occur within the water molecule itself, holding the hydrogen and oxygen atoms together, while ionic bonds and metallic bonds do not apply to the interaction between water molecules.
