I. Data Collection
A. Go to and open the Aufbau Simulation. Your screen should look
like the figure below.
Figure 1.
This window will give you access to the energy level diagrams for many of the elements of the periodic table. Each element
square from element 1, H, to element 48, cadmium, will display the locations of each of the electrons in an atom of the
element. Click on the box for element 12, magnesium. Your screen should look like the figure below.
