explain the reason that the atomic emission spectrum of hydrogen contains only four lines.\na the hydrogen atoms form a continuous series of quantized energy levels that transmute at a variety of frequencies.\nb hydrogen atoms contain a limited number of quantized energy levels that emit radiation at a limited number of frequencies.\nc many hydrogen atoms accomodate an array of quantized energy levels that can release energy at a progression of frequencies.\nd a hydrogen atom consists of a sequence of quantized energy levels that incorporate radiation only from consecutive frequencies.

Answer

Brief Explanations:

  • Option A: Incorrect. Hydrogen atoms do not have a continuous series of quantized energy levels. Energy levels are discrete.
  • Option B: Correct. Hydrogen atoms have a limited number of quantized energy levels. When electrons transition between these levels, radiation is emitted at specific (a limited number of) frequencies corresponding to the energy differences between the levels.
  • Option C: Incorrect. It's not about many atoms accommodating an array in a wrong sense. The key is the discrete energy levels of a single atom (and by extension, a collection of atoms) leading to limited frequencies.
  • Option D: Incorrect. There is no such rule that radiation is only incorporated from consecutive frequencies. The lines in the spectrum are due to electron transitions between any of the quantized energy levels (not just consecutive ones).

Answer:

B. Hydrogen atoms contain a limited number of quantized energy levels that emit radiation at a limited number of frequencies.
