Failure to explain the origin of line spectral phenomenon in atom of elements is the short coming of whose model of the atom

Answer 1

The failure to explain the origin of line spectral phenomenon in atoms of elements is a shortcoming of Niels Bohr's model of the atom. Bohr's model successfully explained certain aspects of the atomic structure, such as the quantization of electron orbits and the emission of discrete spectral lines, but it ultimately failed to fully account for the underlying physical mechanisms responsible for these observations. This limitation led to the development of more advanced atomic models, such as the quantum mechanical model, which provided a more comprehensive explanation of atomic behavior.
