To determine

To Explain: The Bohr model of an atom conflicts with the Heisenberg uncertainty principle, whereas the quantum model does not.

Explanation of Solution

Introduction:

Bohr model considered fixed orbits and trajectories for electrons whereas Heisenberg uncertainty principle not considered those fixed orbits.

Bohr model considered that electrons are at a fixed distance from the nucleus. Heisenberg uncertainty principle states that it is impossible to predict the position and momentum of the electron simultaneously.

On the other hand, quantum model predicts the probability of electron in a specific region. Quantum model predicts the distance between electron and nucleus of hydrogen atom as described by Bohr.

Conclusion:

Quantum model predicted the position of the electron from the nucleus and fixed orbits for an electron as described by Bohr which conflicts the Heisenberg uncertainty principle.
