Water is made of molecules, each consisting of two hydrogen atoms and one oxygen atom. These atoms are chemically bonded together by covalent bonds to form a water molecule with the chemical formula H₂O. The molecule has a bent shape, with the hydrogen atoms attached to the oxygen atom at an angle of about 104.5°. This arrangement makes water a polar molecule, meaning it has partial positive charges near the hydrogen atoms and a partial negative charge near the oxygen atom. This polarity is responsible for many of water's unique properties, such as its ability to dissolve many substances and its relatively high boiling point compared to similar molecules. In summary, water is composed of:
- Two hydrogen atoms
- One oxygen atom
Chemically bonded as H₂O.
