Water molecules are bonded to the central oxygen atom by a pair of electrons that are shared between them.

Positive and negative charges of water are distributed by the four electron pairs surrounding the oxygen tend to arrange themselves as far from each other to minimize repulsions between these clouds of negative change

Insects walk on water because it is like an elastic film that resists deformation when a small weight is placed on it to due to surface tension .

When water is a solid it actually becomes less dense than as a liquid, which makes it unique
