Hydrogen bonds hold together the atoms in a water molecule. A single water molecule is made up of two hydrogen atoms and one oxygen atom.
When a water molecule is formed between hydrogen and oxygen atoms, the oxygen atom ends up with a partial negative charge and the two hydrogen atoms end up with partial positive charges. The hydrogen bonds formed are responsible for the stabilized structure of water.
Water molecules freeze, becoming ice, at 32 degrees Fahrenheit and boil into water vapor at 212 degrees Fahrenheit. Water is an odorless and tasteless liquid that is necessary for sustaining life.
