The Bohr model for the spectra of a H-atom: (a) will not apply to hydrogen in the molecular form. (b) will not be applicable as it is for a He-atom. (c) is valid only at room temperature. (d) predicts continuous as well as discrete spectral lines.
Choose the correct option:
(a), (b)
(c), (d)
(b), (c)
(a), (d)
The Bohr model is valid only for single-electron species (hydrogen-like species) such as the Hydrogen atom, He, and Li . It fails to explain the spectra of multi-electron atoms like the neutral Helium atom (He), which contains two electrons . Furthermore, the model cannot explain the ability of atoms to form molecules (like molecular hydrogen, H) . The model predicts line spectra (discrete) rather than continuous spectra, based on quantized energy transitions . The validity of the model is based on electronic structure, not room temperature.
