Answer

Brief Explanations:

To solve this, we analyze each atomic model:

  • Dalton's model: Atoms are indivisible, no orbit concept.
  • Thomson's model: "Plum - pudding", electrons in a positive sphere, no specific orbits.
  • Rutherford's model: Nucleus at center, electrons move randomly, no specific orbits.
  • Bohr's model: Electrons move in specific, fixed - energy orbits around the nucleus.
  • Quantum model: Electrons in electron clouds, not specific orbits.

So Bohr's model proposed electrons move in specific orbits.

Answer:

D. Bohr’s atomic model
