How does Heisenberg's uncertainty principle conflict with the Bohr model of hydrogen?
Heisenberg's uncertainty principle states that it is impossible to simultaneously know both the exact position and momentum of a particle. In contrast, the Bohr model of hydrogen assumes a well-defined orbit for electrons which violates this principle. This conflict led to the development of quantum mechanics, which describes the behavior of particles more accurately.
Why does the concept of Bohr orbits violate the uncertainty principle?
The Bohr Model of a single-electron atom assumes that the energy levels of electron orbits are fixed due to the quantization of angular momentum of the electron while in orbit. The problem occurs because angular momentum depends on both the radius of the orbit and the velocity of the electron in that orbit. If one or the other is uncertain, then it is impossible to know the angular momentum. Heisenberg showed that either one or the other MUST be uncertain. If we are certain about the radius, we MUST have uncertainty about the velocity -- and vice-versa. Thus, angular momentum of an orbting electron can NOT be quantized, because it can not be known.
The radius of the first Bohr orbit of hydrogen atom is 0.529 AmstraumThe radius of the third orbit of He plus will be?
The radius of the nth orbit in the Bohr model is given by the formula: (r_n = 0.529 \times n^2 / Z), where n is the principle quantum number and Z is the atomic number. For He+, Z = 2 and n = 3, so the radius of the third orbit of He+ would be (r_3 = 0.529 \times 3^2 / 2 = 2.117 Amstraum).

How bhor's theory violates uncertainity relation?
Remember that Bohr's theory on atomic structure was 1) only a model and 2) cannot truly violate anything, as it was only a model. However, the fundamental flaw in Bohr's model is the assumption that an electron of a certain energy level, or "shell", can only occupy that energy level (unless it jumps to another level, requiring energy). This essentially claims to know the relative position of that electron, while Heisenberg's uncertainty principle states that this is impossible. Rather, the electron cloud model is more commonly used today, which gives regions of probability in which it is most likely to find an electron of a given energy level.

What are the statements proposed by neils bohr?
Niels Bohr proposed the quantized electron orbits in the atom, known as the Bohr model. He also introduced the principle of complementarity, which suggests that particles can exhibit both wave-like and particle-like properties depending on the experimental setup. Additionally, he proposed the concept of quantum jumps, where electrons transition between energy levels by emitting or absorbing photons.
