Quick Answer. 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.
These different versions of an element are called isotopes. Nuclei are held together by the nuclear strong force: a kind of 'glue' that operates between nuclear particles. It is not strong enough to bind protons (which repel one another electrically) or neutrons together on their own.
