Question

bohrs model could only explain the spectra of which type of atoms?

single atoms with one electron
single atoms with more than one electron
bonded atoms with more than one electron
bonded atoms with one electron

Explanation:

Bohr's model is based on the hydrogen - like atoms. Hydrogen has one electron. The model works for single atoms (not bonded) with one electron as it simplifies the electron - nucleus interaction. For atoms with more than one electron, electron - electron repulsions come into play which Bohr's model does not account for. Bonded atoms have a more complex electronic environment due to the influence of other atoms in the bond, which Bohr's model also cannot handle.

Answer:

single atoms with one electron
