Chemical properties of water

The chemical formula of a molecule of water is H₂O: two atoms hydrogen (H₂) linked to one atom oxygen (O). The atom electrons (particles with a negative charge) establish links between themselves. Oxygen is more able to keep them close to it than hydrogen. The water molecule results to be charged negatively near the atom of oxygen and positively near the atom of hydrogen. Since opposites attract, the water molecules tend to join together like magnets.
