I have a question about the stability of positronium.
Positronium consists of an electron and a positron whereas hydrogen consists of an electron and a proton. The energy levels of positronium, ignoring fine structure, are -6.8eV/n2 whereas those for hydrogen are -13.6eV/n2.
My question is, why is positronium unstable resulting in the annihilation of the positron-electron pair while hydrogen is stable? Why does positronium not simply remain in its lowest energy level -6.8eV?
