Neon, Argon, and Mercury were tested in three independent experiments. Monatomic gases were used in order to prevent molecular transitions. If a molecular transition were to occur, it is likely that some of the energy lost in the inelastic collisions would results from molecules separating into singular atoms, thus complicating the analysis. A general circuit diagram for the experimental setup is shown in Figure 1, containing all the elements previously discussed. Figure 2 shows the specific circuits used in each experiment. They are all relatively similar, save a few specific modifications. Mercury is the only element for which a heating chamber is required, since it is a liquid at room temperature. Since Mercury is a liquid at room temperature, the heating chamber allows the Mercury to undergo a phase transition so that it is in a gaseous state. Once Mercury is in a gaseous state, electrons can collide with individual atoms, thus it becomes usable in this study. The mean free path, $\lambda$, is dependent on the cross section, $\sigma$, of an interaction and the density, $N$. For mercury, $\lambda$ can be approximated using Eqn 1. 1 \cite{Rapior_2006}.  \begin{equation}\label{eq:MeanFreePathMercury}   \lambda = \frac{k_{B}T}{\sqrt(2)\sigma P}
