Short Answer

Why do Bohr’s calculations for electron energies not work for all atoms?

1. In atoms with more than one electron is an atomic shell, the electrons will interact. That requires a more complex formula than Bohr’s calculations accounted for.
2. In atoms with 10 or more electorns in an atomic shell, the electrons will interact. That requires a more complex formula than Bohr’s calculations accounted for.
