Practice portal › Atoms › Bohr Model of the Hydrogen Atom

Imagine that the electron in a hydrogen atom is replaced by a muon (μ). The mass of muon particle is 207 times that of an electron and charge is equal to the charge of an electron. The ionization potential of this hydrogen atom will be

• (1) 331.2 eV
• (2) 2815.2 eV
• (3) 13.6 eV
• (4) 27.2 eV

Step-by-step solution

Why the other options are wrong

• (1) Scales by a wrong factor.
• (3) Thinks the ionisation energy does not depend on mass.
• (4) Doubles instead of scaling by 207.
