Physics · Dual Nature of Matter and Atoms
The radius of the first permitted Bohr orbit for the electron in a hydrogen atom equals 0.51 Å and its ground state energy equals -13.6 eV. If the electron in the hydrogen atom is replaced by a muon (μ-) [which has the same charge as an electron but a mass equal to 207 me], the first Bohr radius and ground state energy will be approximately:
