2.25 Choose an atomic model to explain a phenomenon and explain why you chose that model.

How would you choose an atomic model to explain a phenomenon, and which one would you use?

Example Phenomenon: Emission Spectra of Hydrogen

• Chosen Model: Bohr’s Model

  • Explanation:

    • Bohr's model is best suited to explain the emission spectra of hydrogen. According to Bohr, electrons in hydrogen atom can only occupy specific, quantized energy levels.

    • When electrons move between these energy levels, they absorb or emit photons of specific wavelengths, corresponding to the energy difference between the levels. This results in the discrete lines seen in the hydrogen emission spectrum.

  • Why Chosen:

    • The concept of quantized orbits directly explains why only specific wavelengths of light are emitted, as electrons transition between discrete energy levels.
