Molecules are held together by electrons shared between bonded atoms. For example, consider the formation of an H2 molecule from two separate hydrogen atoms: 2 approachinghydrogen atoms(2 H) a hydrogen molecule(H2) As the two atoms approach, each nucleus begins to attract the other atom's electrons.
