Water is composed of two elements: hydrogen and oxygen. The chemical formula for water is H2O, which means that each molecule of water consists of two hydrogen atoms and one oxygen atom. The hydrogen atoms are bonded to the oxygen atom by covalent bonds.

A covalent bond is a chemical bond that is formed when two atoms share electrons. In the case of water, the hydrogen atoms share their electrons with the oxygen atom. This sharing of electrons creates a stable molecule of water.

The hydrogen atoms in a water molecule are positively charged, while the oxygen atom is negatively charged. This gives water a polar molecule, which means that it has a positive end and a negative end. The polarity of water is responsible for many of its unique properties, such as its ability to dissolve other polar molecules and its high specific heat capacity.

Pure water is tasteless, odorless, and colorless. However, water that we find in nature often contains dissolved minerals and gases, which can give it a taste, odor, or color.
