Lithium atomic nucleus

The lithium 7 isotope nuclear structure is shown for Blender 3D tools or using the .obj file format. According my theory, protons tend to form lines of protons. That was discovered for iron on May 25, 2017. So lithium is drawn using that rule. Lithium is rare because iron is common. Iron has a cube-3 with its six faces armored by one lithium-5 isotope, each. In a star, iron getters lithium, so Li is the rarest element in the Sun.

Two versions of lithium have the nucleons touching .3% or 4% of the radius r of the proton or neutron.
