What holds combinations of atoms together in molecules?

Explanation: The chemical bonds that hold the atoms of a molecule together are covalent bonds, formed when two atoms share electrons. read more

Covalent bonds, ionic and hydrogen bonds also hold the atoms together. As the molecules share electrons, they are held together by covalent bonds. If the molecule has polar covalent bonds it is also held together by dipole attractions (which are stronger than those of van der Waals forces). read more
