Question
Which of the following is considered a limitation of Bohr’s model? It was unable to explain
- En i.e. energy of the nth shell electron of hydrogen
- ionization energy of hydrogen
- line spectrum of helium
- line spectrum of hydrogen
Answer
line spectrum of helium
Explanation
Bohr’s model was unable to explain the line spectrum of atoms other than hydrogen. While it successfully explained the line spectrum of hydrogen, it failed to account for the more complex spectra of other elements, such as helium.
