What evidence exists that electrons are found in quantized energy levels?
A) Line spectra of all the primary colors
B) Line spectra with a limited number of lines of color
C) Continuous wave spectra from photons
D) There is no evidence for this.
Line Spectra
Line spectra are the emission or absorption of light at specific wavelengths by atoms or molecules transitioning between energy levels, resulting in distinct lines characteristic of the substance.
Quantized Energy Levels
The concept in quantum mechanics that energy levels in atoms and molecules are discrete, not continuous.
- Recognize and explain electron behavior in quantum states including quantized energy levels and orbital shapes.

Final Answer :
B
Explanation :
Line spectra with a limited number of lines of color provide evidence for quantized energy levels. When electrons in an atom transition between these levels, they emit or absorb photons of specific energies, resulting in discrete spectral lines rather than a continuous spectrum. This phenomenon cannot be explained without the concept of quantization.
