bohr used the emission spectrum of hydrogen to support his idea that\na electrons travel around the nucleus in a circular orbit.\nb electrons move in discrete energy levels around the nucleus.\nc there are a limited number of energy levels an electron may occupy.\nd the energy of an electron is related to its distance from the nucleus.
Answer
Brief Explanations:
Bohr's model proposed that electrons occupy discrete energy levels. When electrons transition between these levels, they emit or absorb specific amounts of energy, which is seen as discrete lines in the emission spectrum. Option A is too simplistic (not just circular orbits but quantized energy levels). Option C is incorrect as there are an infinite number of energy levels (though they converge). Option D is a partial truth but not the main idea supported by the emission spectrum. The key idea from the emission spectrum is the discrete energy levels (Option B).
Answer:
B. electrons move in discrete energy levels around the nucleus.
