CHAPTER X

THE OCTAHEDRON GROUP B

THESE elements occur at the extreme left-hand swing of the pendulum. Their characteristic valence is four. They all have eight funnels opening on the faces of an octahedron and two of them add spikes pointing to the six corners.

SILICON AND GERMANIUM

atomic no. 14. SILICON

Silicon is at the head of the group and corresponds to Carbon on the opposite extremity of the swing of the pendulum. It has eight funnels containing a group of five Anu, B5, and four ovoids in a circle, Sil5, but no central sphere of any kind. All the funnels are alike and open on the faces of an octahedron. Fig. 131.

Central globe. In this case the funnels radiate from a central globe formed of two intersecting tetrahedrons, 2Ad24. These tetrahedrons enclose a tiny globe of four Anu. Fig. 131.

Funnels. There are eight similar funnels each consisting of four segments. The segments are similar and contain three ovoids Gell and an Ad6. Thus the segments each contain 39 Anu. This group, Ge39, occurs frequently.
