Which models of the atom does the experimental evidence support? Explain why these models are compatible with the experimental results. Part B Which models of the atom in task 1 are not supported by the results of the hydrogen gas experiment? For each of these models, explain the experimental results that the model would predict.

Question

Part A
Recall all the models you described in task 1. Think about the results each model would predict for the experiment with hydrogen gas. Which models of the atom does the experimental evidence support? Explain why these models are compatible with the experimental results.


Part B
Which models of the atom in task 1 are not supported by the results of the hydrogen gas experiment? For each of these models, explain the experimental results that the model would predict.


Models in task 1: 
- Dalton’s Atomic Model
- Thomson’s Atomic Model
- Rutherford’s Atomic Model
- Bohr’s Atomic Model

Gas Discharge Tubes
410 nm 434 nm
486 nm
656 nm
A gas discharge tube consists of a gas-filled tube fitted with a metal electrode at each end. In this case, the
gas used is hydrogen. An electric current is passed through the tube. The electrons in the hydrogen
absorb energy from the electric current and get excited to a higher energy level. As the electrons return to
their original energy state, called the ground state, they emit light of a specific color. The color of the light
depends on the amount of energy that it carries. This energy is the difference in energy of the excited
state and the ground state. Particles of different gases emit light carrying different amounts of energy
and, as a result, different colors. Hydrogen emits four visible colors of light.
