Water structure refers to the arrangement of water molecules, which consist of two hydrogen atoms bonded to one oxygen atom, forming the chemical formula H2O. The unique shape of the water molecule, with a bent geometry, leads to polar characteristics, meaning one end is slightly positive and the other slightly negative. This polarity allows water molecules to form hydrogen bonds with each other, creating a cohesive structure. These hydrogen bonds give water its distinctive properties, such as high surface tension and the ability to dissolve many substances, making it an essential solvent in biological and chemical processes. The structure of water also plays a crucial role in regulating temperature and supporting life on Earth.
