In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

When an oxygen atom joins with two hydrogen atoms to make a water molecule, it shares an electron with each. But it also has electrons it doesn't share. As a result, the water molecule has + and – poles, like a magnet. These poles attract each other, forming weak links called hydrogen bonds.

Adhesion: Water is attracted to other substances. Adhesion and cohesion are water properties that affect every water molecule on Earth and also the interaction of water molecules with molecules of other substances.

The maximum number of molecules that one water molecule can hold through hydrogen bonding is 4 because the two hydrogen atoms of water can form two hydrogen bonds and the two lone pairs on oxygen can also form two hydrogen bonds.

We think of water as H2O, but water molecules are constantly reacting with each other and changing. When two water molecules react, a proton from a hydrogen atom in one water molecule transfers to the oxygen atom in the other water molecule.

What will happen when two water molecules bump into each other? When the oxygen atoms of 2 different water molecules come together, they repel. When the hydrogen atoms of 2 different water molecules come together, they repel.
