In the periodic system as a whole "the octet rule" creates
one of the fundamental polarities. (Other ones are the fusion 
fission "directions and lightest  heaviest elements. NZrelations
may be regarded as a third.)
The octet rule separate more or less oxidation
numbers, valences and defines the difference between nonmetals
and metals. It has been described as a "striving" of the
atoms for filled s and pshells furthest out and cannot be explained
by the elementary balance between numbers of protons in the nucleus
and electrons in the shell. Inert gases have this figuration; 2
+ 6 electrons, one sorbital and one filled porbital furthest out,
which gives a "complete" shell, stability, indisposition
to react with other atoms.
From a purely electromagnetic point of view the equal number of
protons and electrons itself in every element could have been thought
of as making them "selfsufficient". It doesn't. Nor does
the structure of orbits according to the reference above. We have
to look for some other determining factor.
Why do 8 electrons furthest out represent the most stable configuration,
defining whole shells? Here some suggestions.
:
a) Ddegree 2, giving number 8 in the 2x^{2}chain,
represents geometrically surfaces,
the character of "shells". May be interpreted as disintegrating
into 6 + 2.
b) 3 polarizations lead to number 8 in the 2x^{2}chain.
3 polarizations in the2xchain the same: 1 →2
→ 4 →
8, as in ddegrees from 0/00 → 1
→ 2 →
3.
c) In our model ddegree 2 has the outer poles (or partial structures)
3a and 3b:
3a—2 —3b: possible to read as 2 + 6.
d) 3 angle steps from 360°  →180°→
90°→45° implies an 8division
of a circle.
This angle 45° doesn't appear in the orbit structures of
s and p above but with the forbital (in
step 43 in the number chain).
In the loop model we have the connection between
step 4 → 3 and 2←
1.
Loopmodel: Step 5→
4 corresponds to step 1← 0/00 (s)
,
step 4 → 3 corresponds
to step 2← 1 (p).
Fig. 052:
Could the completeness of the number 8 eventually be connected
with the fact that the coefficient of direction at 45° is 1,
sin = cos? A balance between directions "inward /outward, poles
of ddegree 4 in our model, as they appear in ddegree 2?
e) 8 space quadrants make up a full, complete Volume (ddegree
3). In the forbital only 2 electrons, each with 4 lobes, occupy
these solid angles as noticed above. This fact could be thought
of as translated into the s+porbitals in the lower degrees.
f) Charge as such, as one of the elementary
properties of matter, has in this model been assumed as a 2dimensional
one in relation to mass when analyzed as 3dimensional.
If so, could this imply that ddegree 2, giving number 8 in the
2x^{2}chain, constitutes a certain border; electron shells
as expression for total positive / negative charge?
Mass Charge +/
g) A related aspect refers to views on development in this model:
from Forces to Mass to Matter of opposite Charge etc. The electromagnetic
force assumed to develop in ddegree step 3  2 with elementary
particles of "matter" as p and e appearing in ddegree
2. In following step 2  1 we could assume the differentiation of
chemical elements. in next step molecules.
h) Charge as property has naturally roots in higher degrees as
ddegree 4. The elementary polarization of ddegree 4 may be written:
4 → 3+1. These figures doubled give
6 + 2, the numbers for p + sorbitals.
With these a bit different aspects we reach number 8 In several
ways towards the middle of the chain (3 or 2) from higher or lower
ddegrees, the kind of centre where directions outwards and inwards
meet in the loop model.
Oxidation numbers and ionizations depend more
or less on this "octet rule".
Worth noting is that e.g. Cl (17 Z) as a ion Cl , with 6 e furthest
out, that is with "completed" s + porbitals, has a bigger
radius than Ar 18 Z. Hence, the "stolen" electron doesn't
supplement the porbital into symmetry, nor to inactivity. The number
8 itself doesn't explain the inertia of the inert gases. Elements,
which through ionization get the full s+pnumber 8 furthest out,
as Cl, K+, Mg2+ etc. etc. are actively involved in molecular processes,
those gases not.
Only where this number 8 or filled s+porbitals
in outer shell coincides with the equivalence between number of
protons in nucleus and electrons in the shell, the inertia appears.
The geometry of filled porbitals may be one factor.
Generally speaking, we should count on dimension chains developed
on many different levels and with different relations in the steps,
expressed as operators of different kinds working in the ddegree
steps. Then the octet rule could perhaps express such a conjunction
between two (or more) levels or properties. One example:
In the dimension chain as Force times Distance
(an 1dimensional potential) the products led to the same number
8 of s + p:
5 x 4 = 20, 4 x 3 = 12, the lower steps 3 x 2
= 6, 2 x 1 = 2.
On a deeper level, in a dimension chain of forces, the strong force
(Fst) has been assumed developed in ddegree step 21. With the
electromagnetic force regarded as developed in step 3  2 and Charge
as property in ddegree 2, the first polarization of charge in protons
and electrons becomes a condition for the development of the strong
force. Cf. the outer poles of ddegree 2 = 3 + 3 = 6: 3a —
2 — 3b . We could perhaps
imagine that such processes on different levels coincide at ddegree
2, defining the octet rule?
Could there exist some connection too between the octet rule and
the fact that the strong force in nuclei isn't fully developed before
» 8 protons?
Transformations of numbers between numberbase systems (nbx):
As said above: the possibility of a connection between different
ddegrees and different numberbase systems (built on Enumbers
as sum of poles) has been developed in the files about the genetic
code, the possibility of an inherent mathematical operator on an
underlying level to physics and biochemistry (?).
The 2x^{2}series behind electron shells read as 8basenumbers:
Intervals in the 10base number chain:
= forbital 14, dorbital 10, s+porbital 8, porbital 6 (+ sorbital
2).

6. Factor 21 and Zsums divided on elements in different orbitals:
Bi, 83 Z, is often regarded as the highest "stable" element.
The whole sum of 1  83 Z =
= 3486 Z.
This sum is divided on the elements in different orbitals like this:
forbital elements 21
x 43 = 903
spdorbital elements 21 x 123 =
2583 = s 258 + p 894 + d 1431. (s 258 = 6 x 43.)
Note the factor 21 [factors 7 (4+3) and 3 (2 +1)].
