Exotic atoms and molecules
Exotic atoms and molecules are forms of basic matter in which one subatomic particle is replaced by another with the same charge. For instance, an electron can be replaced with a muon, a pion or an antiproton. Positronium is made by swapping the proton in a hydrogen atom for a positron.
