Radon nuclear structure theory

The important element thorium is based on the radon foundation nucleus.
Radon is a gas with a half-life of less than 4 days for all isotopes.
The theory is not approved by educators or any people. The radon nucleus
has a mass number of 220 for the Blender 3D and .obj files for 3D printers.
This model uses the modules provided in 3 loads, previously: cube-3,
pyramid-2, pyramid-3, and the dilated composite pyramid from polonium.

Added protons bring Z to 86 for Rn 220. The protons go in the center
of the cube and on the pyramid-3, plus a long island line of protons
on two sides of the Rn nucleus. This nucleus is shaped like a dart or a jet engine.
It has a nose and a tail end, shown on the top and bottom locations in this thingiverse. A collision of radon with some matter approaching the nose end will hit the armor of the pyramid-6 or it can hit a tip of a pyramid-3, causing decay.

Experimental evidence shows a "pear shape" for the nuclear structure of
Rn. See this paper
