The Bohr model cannot predict spectra for multi electron atoms because Bohr model does not consider forces due to interelectronic attraction between electrons .
The primary problem with Bohr's model is that it performs admirably for atoms with just one electron, such as H or [tex]He ^{+}[/tex], but appallingly poorly for atoms with multiple electrons.
We can predict the energies of each line in the hydrogen atom emission spectrum . The Bohr's model estimate the energy difference between each energy level. These atoms are all made up of two electrons in an outer s-shell in addition to an electron core.
