Molecules
A molecule is a bonded conglomeration of atoms in tentative relationships. 37 distinct types of chemical reactions are known.
When atoms and molecules undergo chemical reactions, the electrons are the ones that do the heavy lifting. They regroup and move to allow new bonds between molecules to be created or destroyed. ~ Swedish atomic physicist Marcus Isinger
Empedocles considered chemical changes as emotional relations: substances combine in love to birth something new, or discordantly divorce. No wonder it’s called chemistry.
Nature does what must be done to achieve equilibrium, which is a minimum-energy configurational space. ~ American chemist Scott Chambers
