Following are the limitations of bohr model of atom.
▪ It is only applicable for Hydrogen and hydrogen like species. He didn't look in to multielectron species.
▪ Bohr model could not explain Zeeman and Stark effect.
▪ It contradicts Heisenbergs uncertainity principle. It states that both velocity and position of electron can't be precisely determined simultaneously. But Bohr gave formula for both.
▪ Although he proposed the existance of stationary states where it's angular momentum is integral multiple of h/2π, he could not explain it's reason.
▪ His model was two dimensional while atom is actually three dimensional. Also he neglected dual nature of electron by considering it as a particle.
