Logic of the Alexander Arrangement of Elements
Forever Periodic Table

By employing the third dimension for accuracy and motivation,
the 3D Forever periodic table;
adheres to the Mendeleev periodic law's: "
...arranged according to their atomic mass
" requirement, displaying a continuous and contiguous series of element data boxes - and blocks as well.

permits correct placement of the f-block within the main body of the table, while staying a physical entity as well.

displays the Main Group blocks connected from top to bottom for enhanced trends observation and understanding.

has an attractive, novel, and motivational appearance of what is more accurate than any other known element arrangement.

uses an element row slant (patented) in the d-block, connecting each period's last element to the first of the next period, following the s-p-d-f block sequence.

is a reference and learning tool that most closely reflects the paradigm of very first periodic table by de Chancourtois, the elements on a continuous helix, or spiral.

employs student interaction to see and learn all the element and block relationships in a tactile as well as visual way.

Logic of the standard flat periodic table

By limiting the periodic table to two dimensions for production convenience and wider distribution, the flat chart;
adheres to the Mendeleev periodic law's: "
...arranged according to their atomic mass...
"requirement
but only when arrows, asterisks, or lines are employed at elements 1, 2, 3, 4, 5,10, 11, 18, 19, 36, 37, 54, 55, 56, 57, 70, 71, 86, 87, 88, 102, and 103.
element blocks are in s-d-p- sequence, and elements of the f-block are completely detached from the others.
the Main Group blocks appear at opposite ends of the chart, making trends observation and understanding more difficult by wide separation of the key main group elements.
it is an icon of educational difficulty - and a method of concept or object arrangement that suits many varied popular non-scientific interests - which are greatly enhanced by its characteristic visual awkwardness.
allows a pragmatic reference and learning tool to become the most common visualization of the relationships among of elements, much like world maps, which are helpful and common versions of the world globe, regardless of distortions (polar regions) and misinformation (relative continent size/shape) in numerous areas.
permits observation of all elements at one time on a flat surface, of great economic and educational value, but exhibits a block sequence of s-d-p plus f-.
