Answer to Question 1

E

Answer to Question 2

The Bohr theory had important limitations. It was not able to predict line spectra for more complex atoms. Nor could it explain why emission lines, when viewed with greater precision, consist of two or more very closely spaced lines. It did not explain why some spectral lines were brighter than others. And it could not explain the bonding of atoms in molecules or in solids and liquids.
