trons that were on the vertices of the alpha particle have no<br />

need to leave. However, any additional neutrons will place<br />

themselves at the centers of the faces of the cube, which is<br />

the same place as the midpoints of the edges of the larger<br />

tetrahedron. (<strong>The</strong> smaller tetrahedron is called the alpha<br />

particle.) Thus, at 6-carbon-12, there are two neutrons on<br />

the alpha particle and four on the faces of the cube (Figure<br />

15)." For clarity, here is another example: the proton structure<br />

of 8-oxygen-16 (Figure 16). Of the eight neutrons, two<br />

are on the inner alpha particle and six on the midpoints of<br />

the six edges of :he larger tetrahedron (or, the same thing,<br />

the face center; of the cube), marking the completion of<br />

this shell. <strong>The</strong> e ght protons locate on the eight vertices of<br />

the cube. Thus, not only is oxygen highly symmetrical with<br />

respect to its pr )ton configuration, but also one of its neutron<br />

shells is co nplete.<br />

Now, to go o i to the end of the period, there are only<br />

two more place ; where the neutrons can go: that is, on the<br />
