What energy holds atoms and molecules together?
Extending that even further, we see that some atoms want to loan out or borrow electrons to set up conditions in the electron cloud where the electrons are “happy” with the arrangement. And this gives rise to chemical bonding, which is the loaning or borrowing of electrons in ionic bonding, or the sharing of electrons in covalent bonding. In the quantum mechanical universe of the atoms, it is electromagnetics that sets the conditions for structures, both of the atoms themselves, and the molecules they form.
