Logic Comparison of the Forever vs. the flat periodic table


Logic of the Alexander Arrangement of Elements
Forever Periodic Table

leading
By employing the third dimension for accuracy and motivation,
the 3D Forever periodic table;
bulletadheres 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. 3D FOREVER PERIODIC TABLE rotation video option

bulletpermits correct placement of the f-block within the main body of the table, while staying a physical entity as well.
leading
bulletdisplays the Main Group blocks connected from top to bottom for enhanced trends observation and understanding.
leading
bullethas an attractive, novel, and motivational appearance of what is more accurate than any other known element arrangement.
leading
bulletuses an element row slant (patented) in the p-block, connecting each period's last element to the first of the next period, following the s-p-d-f block sequence.
leading
bulletis 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.
leading
bulletemploys student interaction to see and touch, thus learn all the element and block relationships in a tactile as well as a visual way.

Logic of the standard flat periodic table
leading
By limiting the periodic table to two dimensions for production convenience and wider distribution, the flat chart;
bulletadheres to the Mendeleev periodic law's: " ...arranged according to their atomic weights... "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.
Modern PT with gaps wired closed
bulletinstead of s-p-d-f-, element blocks are in s-d-p- sequence, with the f-block completely detached.
leading
bulletthe Main Group blocks appear at opposite ends of the chart, making trends observation and understanding more difficult by wide separation of key element groups.
leading
bulletis like geographical maps, which are helpful 2D working guides, however distorted in map projections of the whole globe. Faults are inherent in flat representations of a 3D object. Representations of Earth have polar region misinformation and/or incorrect relative continent size/shape. Mapping the whole of the 3D Periodic Table to a workaday flat surface results in similar problems: a dozen numeric sequence breaks and gaps, separation of the Main Group blocks, and total displacement of the f-block.
leading
bulletpermits observation of all elements at one time on a flat surface, of great economic and educational value, an excellent reference tool, and as necessary as the outdated atom shell concept for instruction.


Whats that, she said, the periodic table the way it's supposed to be but isnt?
