Question

which statement describes a major drawback of the bohr model that caused scientists to replace it?

it worked only for helium and larger atoms.
it did not identify the distance between an electron and the nucleus.
it contradicted the heisenberg uncertainty principle.
it stated that spectral lines of atoms are similar.

Explanation:

flaw leading to the model's replacement. The other options are incorrect: the Bohr model only worked for hydrogen (not larger atoms), it did define electron-nucleus distances, and it explained distinct spectral lines, not similar ones.
