Question

1. for the thomson’s plum pudding model, click on the model and repeat steps 5 - 9 form part 1 above and perform the same comparison analysis. you will be taking a snapshot of this model. what happens when photons interact with the atom in this model? select all correct responses on d2l. you should let the simulation run for ~1 minute with white light, then take a snapshot & save it. describe the resulting emission spectrum from thomson’s plum pudding model. is it “right”? explain the emission wavelengths from the spectrometer and compare to experiment from part1. written response on d2l

Explanation:

In Thomson's Plum - Pudding Model, atoms were thought to be a uniform positive charge with electrons (the "plums") embedded in it. When photons interact with the atom in this model, electrons could absorb the energy of photons and move to higher energy states and then emit photons when returning to lower states. The resulting emission spectrum would be continuous as there were no distinct energy levels assumed in this model. In reality, atomic emission spectra are discrete, so the spectrum from Thomson's model is not "right". The spectrometer would show a continuous range of wavelengths in the simulation of this model, which is different from the discrete line - spectra observed in experiments.

Answer:

When photons interact with the atom in Thomson's Plum - Pudding Model, electrons can absorb and emit photons. The resulting emission spectrum is continuous and it is not "right" as real - world atomic emission spectra are discrete.
