We choose to go to the muon Chemists Mohammad Goli and Shant Shahbazian posit two new light elements. They are muonium (Mu), in which an electron orbits a positively charged muon ( +), and muonic helium (He ), in which an electron orbits a 'nucleus' consisting of an alpha particle and a negative muon. |
