2. Atom - Wikipedia

   en.wikipedia.org/wiki/Atom

   Atoms can attach to one or more other atoms by chemical bonds to form chemical compounds such as molecules or crystals. The ability of atoms to attach and detach from each other is responsible for most of the physical changes observed in nature. Chemistry is the science that studies these changes.

   en.wikipedia.org/wiki/List_of_particles

   Leptonic atoms, named using -onium, are exotic atoms constituted by the bound state of a lepton and an antilepton. Examples of such atoms include positronium (e − e +), muonium (e − μ +), and "true muonium" (μ − μ +). Of these positronium and muonium have been experimentally observed, while "true muonium" remains only theoretical.
