what is water made of?

Water is made of molecules, each consisting of two hydrogen atoms and one oxygen atom, giving the chemical formula H2O. The atoms are bonded covalently, with the oxygen atom having a partial negative charge and the hydrogen atoms having partial positive charges, making the molecule polar. This polarity leads to hydrogen bonding between water molecules, which gives water many of its unique properties such as its high boiling point and ability to dissolve many substances.
