The Single Helix
Chemical Element System data
for Periodic Table Applications
The natural atoms can only be arranged
with all element relationships perfectly
correct by spiralling every element
down a single helix on a 3D model,
groups aligned and elements contiguous. Flat periodic tables currently employ this
systemized data in the more convenient
2D tabular format necessary for easier
printing, study and work of Chemistry.
The differences between flat periodic tables
and the three-dimensional system model
photographed to illustrate this principle in
the views at the right have been annotated
to the right of the photos. Swipe to see more, and click on the

The stretched and wrapped
Hydrogen box (originating from
nothing at the Big Bang) unites
with Helium ,completing the first period,
atop the 8 period Main Group
element tower at the left.
While the D- & F-blocks (on the right) are each independent, connecting with each other and to both S-block's Group IIa in the single vertical location I call the neXus results in the Atomic Numbers of the Element Line being continuous from start to finish while keeping all vertical property group columns intact as well. Instead of being at the edges of the periodic table, both the ends and beginnings of the periods are together - greatly improving trends teaching - and that junction is clearly defined by the period arrows pointing to the last and next periods on the corner bars between Groups 18 & 1.
Hydrogen's unique extended databox
makes explicit the concept that
Period 1 is quite different from the
following periods, and by circling over
the Main Group, the easy combining
with those elements is implied.
In the Big Bang, Hydrogen, first, then Helium then Lithium are thought to have been realized first, the same order illustrated from top down in this model, rather than being separated on common periodic tables.
Explicit in the Periodic Law, numerically contiguous elements are only available in 3D models of the Alexander Arrangement, shown at left in the slant of P-block databoxes. This patented feature is what allows period ends to physically connect with the next period's first element
- a key trends factor that flat periodic tables sacrifice in exchange for all elements to be visible at one time.
Seeing all element information at once
on a convenient surface is vital to the
doing of chemistry, but for the initial
introduction and understanding of the
correct relationships among both
elements and blocks, models of the
Alexander Arrangement of Elements
are required to show Mendeleyev's
Periodic Law as well as the S P D F
top down subshell order.
Large databoxes names, symbols, and numbers for Howard Gardner's verbal-linguistic, while Theodore Gray's 'prior knowledge' photography appeals to those with naturalistic competencies.
At the same time, the physicality of this model requires manipulation - attractive to the bodily-kinesthetic as well as visual-spatial intelligences - adding these groups to others for whom the common flat periodic tables' awkward form may be a disappointment, or deterrent.
Instead of Main Group blocks
being pushed apart by the
transition metals, common in
periodic tables, the other block
loops being pinched where they
join between Groups 2 & 3
avoid that distortion (center).
Feeling and seeing the natural beauty of science, which are expressed in this model - either as a great periodic table or a model of the reality of the atoms/elements systematized according to the Periodic Law - provides greater understanding and appreciation of Science.
Flat periodic tables show all elements at once, giving us an unbeatable work platform, while this 3D model requires hands-on to see all elements - adding respect for the Periodic Law and a glimpse of reality.
The unique form and function of the
Alexander Arrangement of Elements
shows best from the top.
The extended H databox originates from nothing (like the Big Bang) inside the Main Group tower, rising clockwise to touch on He, Li, and Be, and descends in the P-block (where the Alexander downslant takes place in all periods) to rest against HE. The crossover of the blocks at the neXus shows the attachment of S- block's Group IIa to the first elements (Groups IIIa,b,c) of the other blocks.
In nature - I imagine - the neXus block connections would include both the first elements of the s-block, and the end elements of the D-block, instead of the AAE model's joining of them for datablock readability at the left corner of the S-block.
