What does the observation of line spectra occurring in doublets and triplets suggest?

Options

  1. AIt suggests the presence of additional electrons.
  2. BIt suggests the presence of additional energy levels beyond those predicted by the three quantum numbers.
  3. CIt suggests the presence of electromagnetic radiation.
  4. DIt suggests the presence of isotopes.

Correct answer

B. It suggests the presence of additional energy levels beyond those predicted by the three quantum numbers.

Step-by-step solution

The occurrence of line spectra in doublets and triplets suggests that there are additional energy levels in multi-electron atoms beyond what is predicted by the three quantum numbers.
