Fifth

At the end of the end-ring of the five double-ring branches are three sets of Eight-One combinations, attached to the three Sixes that are directly opposite the Six attached to by the structural Six. This lowly Six is bent by a double-attached Eight, and a single-attached Eight that bonds to the other ring. This makes an odd angle.

It's the triple of Eight-One combinations that catch my interest. With one side of the Eight attached to a Six in the ring, the solo Electron that belongs to the one on the opposite side of the eight, spends much more time on the eight, exposing the proton of the One for the world to see. This makes the outer Eight-One pairs push away from the central pair, creating a fan out, that is capable of attracting the negative side of loosely coupled atoms that can be found with an extra Electron.

Seventeens, Twenties, and oddly enough, the Eight-One has a strange affinity for One-Eight-Ones as a whole. Grabbing them until they get so anxious that they jump away from their brothers in flight acting like a pair of Sevens, the slippery devils that are the One-Eight-One demonstrate their notorious abilities.
