(N/A) The Bohr model fails for the following reasons:
$1$. It treats the electron as a charged particle and ignores the wave character of the electron.
$2$. It assumes that electrons move in well-defined circular orbits. According to the Heisenberg uncertainty principle,it is impossible to determine both the exact position and the exact velocity of an electron simultaneously.
$3$. The model ignores the dual behavior of matter and contradicts the Heisenberg uncertainty principle. Consequently,it cannot be extended to multi-electron atoms.
