Given below are two statements:\n Statement I: An orbit as proposed by Bohr is a defined circular path around the nucleus, whereas an atomic orbital is a three-dimensional region representing probability distribution.\n Statement II: Bohr's orbits can be experimentally demonstrated, while atomic orbitals cannot be visualized as physical trajectories. \nIn the light of the above statements, choose the most appropriate answer from the options given below:

  1. Both Statement I and Statement II are correct.
  2. Both Statement I and Statement II are incorrect.
  3. Statement I is correct but Statement II is incorrect.
  4. Statement I is incorrect but Statement II is correct.

Correct answer · Option 3

Statement I is correct but Statement II is incorrect.

Explanation

Statement I is correct. Statement II is incorrect because Bohr's orbits violate the Heisenberg uncertainty principle and their existence cannot be demonstrated experimentally.
