The Single Helix
para spacer Chemical Element System data
for Periodic Table Applications

para spacer The natural atoms can only be arranged
with all element relationships perfectly
correct in a model by spiralling every element
across one row - in a single helix.
para spacer Flat periodic tables currently employ this
systematic data in the more convenient
2D tabular format necessary for easier
printing, study and work of Chemistry.
para spacer The differences between 2D periodic tables
and the three-dimensional system model
photographed to illustrate this principle in
the views at the right have been annotated.

Chemical Element System para spacer The Hydrogen box has been stretched and wrapped to maintain atomic number sequence with Helium, uniting the first period, atop the 8 period Main Group element tower at the left.
para spacer Instead of being at the edges of periodic tables, the ends and beginnings of the shells/ periods are together - greatly improving trends teaching - and clearly defined by period numbers pointing in both directions on the corner bars between Groups 12 & 1.
para spacer While the D- & F-blocks (on the right) are each separate, their atomic numbers stay sequential between them and with other blocks by each connecting to both Main Group blocks in a single vertical location - to the right of Group 2 (center).
Chemical Element System para spacer Importantly, periodic tables show all element information at once, but to feel and see the same data within the physical grace of this model requires a physical interaction - which is attractive to those favoring Howard Gardner's bodily-kinesthetic as well as visual-spatial intelligences - adding these groups to others for whom the common IUPAC style periodic tables' awkward form is a deterrent.
para spacer Large databoxes provide informational text for the verbal-linguistic, while Theodore Gray's object photography appeals to those with naturalistic competencies - plus, recognizable objects promote transfer of learning by introduction of the familiar to new context, easing entry to science for students as well as other laymen.
Chemical Element System para spacer Hydrogen's unique extended databox of this model makes explicit the concept that Period 1 is quite different from the periods on the Main Group (S- & P-blocks) below.
para spacer 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.
para spacer The one databox deep downslant feature of the P-block elements is what allows both ends of sequential shells/periods to connect, enablng numerically continuous and contiguous elements - a factor that is explicit in the Periodic Law, but can't be fully complied with in 2D periodic tables.
Chemical Element System para spacer para spacer 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).
para spacer 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.
para spacer 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.
Chemical Element System para spacer Touching above and then fully to the side of Helium, to half of Fluorine, and to the corner of Neon, some of the final Hydrogen databox connections are best seen in this down- slant evident view of the system model : P-block at the center, D-block to the left, and F-block at right.
para spacer This photograph also clearly shows the elements' helix producing downslant which takes place only in the P-block, but might be on any part of the Main Group elements in order to qualify as an accurate depiction of the chemical element system:
para spacer A model with all sequences of atomic numbers and element groups in continuous and contiguous arrangement, complying fully with the Periodic Law.
