Question

What property of spectral lines can Bohr’s model not explain, despite predicting frequencies for hydrogenic atoms?

Options

• Their relative intensities

• The discrete energy levels in a hydrogen atom

• The frequencies of light emitted by hydrogenic atoms

• The existence of selectively absorbed radiation frequencies

Answer 1

Bohr’s model correctly predicts frequencies of light emitted by hydrogenic atoms. It cannot explain the relative intensities of their spectral lines.
