Neon-20 the forth most plentiful nuclide

  • Hydrogen
  • Helium
  • Oxygen
  • Neon
  • Nitrogen
  • Carbon

This list of the six most abundant elements in the universe are marked off with yellow to denote them as SUPER Stable nuclides.


One of the first concepts I've wanted people examine is Stability by Degree, that beyond being stable a nuclide may exhibit distinct qualities of durability in a range of durability.
I introduce the yellow color code to delineate this, the tan color denotes a stable nuclide and the orange the most common isotope of an element if not marked off with yellow as "SUPER Stable".
The pink color denotes a radioisotope with half-life measured in years, the purple denotes those isobars of half-life measured in days. Next is a light blue for nuclides of even faster decay and this shades to white for those that hardly exist for microseconds.
The format for dipicting data this way is named "The Incremental Table of Atomic Isobars" the display lends to metaphor that nature favors the Isobars as a geometric form. From this point of view I have asked people to examine why nature does not favor the existence of an isobar-5 as an exercise in this metaphor.

I post this next table to illustrate

All Isobars to six












I tend to view all the neutrons and protons of an atomic nucleus, while they exist in and as the nucleus the same. That is I do not view them as charge specific nor quark composite specific. I view them as fluid to some degree. The quality that I do impart to them is they still must fill space, and so I tend to the use of the term "isobar" instead of isotope yet use the the term nuclide when need of reference to a specific atom.
The Platonic and Archimedean solids are omnipresent in nature, they represent equal division of a sphere. Well that said please examine with the term isobars in mind the lack of stable nuclides
in the isobar-5 and isobar-8 zones.

-4 -3 -2 -1 n=p +1 +2 +3 +4
He-3 H-3
Li-4 He-4 H-4
Li-5 He-5
Be-6 Li-6 He-6
B-7 Be-7 Li-7 He-7
C-8 B-8 Be-8 Li-8 He-8
xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx


Consider please these two examples of Platonic solids. They as a set exhibit the potential for the sphere to be divided equaly by twelve and twenty. Can it be the best explaination for the favoredness by nature of the isobars 12, 14, 16, and 20 is plain old geometry!

You see at left additions to the chart,
some radionuclides are included now. Oxygen exists in three stable isotopes
O-16, O-17, and O-18. This is the first element thus far looked at being lent to having more than two. This is worth mentioning now before taking a backward look to the sequence of isobars we have now covered.

Carbon-14, a well known isotope is a long lived radionuclide with two extra neutrons. You may notice that the Carbon 12-13-14 relationship mimics that of Oxygen 16-17-18. If Nitrogen presented the same quality its series would be 14-15-16. One could suppose that N-16 has the potential to be stable if it were not for the SUPER Stable O-16, that is to say the extream favoredness of O-16 is involved with the "cause" of the beta decay of N-16.

Carbon-14 on the other hand is alowed a longer half-life, N-14 being stable but not so favored as O-16. Try a look at Boron 10-11-12, Boron-12 is not stable even in terms of long lived radionuclides. Two effects are at work here, with a lighter element n=p+2 may preclude that nuclide, and the involvement of the very favored C-12.
Below is excerpt isobars 10-11-12 from the Incremental Table of Isobars.

Here you may say; "OK, I get the point, yes there are patterns and they have significance." I do suggest that the cause is not singular. I propose that we seek an intergrated set of causes that produce a composite effect.
