Question Detail
Question
Which of the responses contains all the statements that are consistent with the Bohr theory of the atom (and no others)? (i). An electron can remain in a particular orbit as long as it continually absorbs radiation of a definite frequency. (ii). The lowest energy orbits are those closest to the nucleus. (iii). An electron can jump from the K shell (n=1) to the M shell (n=3) by emitting radiation of a definite frequency.
Correct Answer
Option B is the correct answer.
Detailed Explanation
Statement (i) is incorrect because an electron in a stable orbit does not absorb or emit radiation. Statement (iii) is incorrect because jumping from n=1 to n=3 requires absorption of energy, not emission. Statement (ii) is correct: lower energy orbits are closer to the nucleus.
Hint
Bohr's postulates: electrons in stable orbits do not radiate; energy is emitted or absorbed when jumping between orbits.
