The Alexander Arrangement of the Elements View your shopping cart

The Alexander Arrangement of the Elements is an improved periodic table which eliminates the confusion and inconsistencies of the flat table by arranging the elements in order, with successive elements touching, while keeping the accepted groups and families. The 3-D form has three parts looping outwards from a middle area.  The elements in Groups 0, Ia, IIa, IIIb, IVb, Vb, and VIIIb are in the narrowest and tallest part, which forms a tube, topped by a crown of Hydrogen. From the lower part of this branches a longer loop showing groups IIIa, IVa, Va, VIa, VIIa, VIII, Ib, and IIb. From the lower half of this, a third, the longest loop is the f-block, displaying the Rare Earths. The successive element connections are achieved by the patented downward helix in the first of the three components. Also notable is the superior position given to Hydrogen, implying its multiple relationships and upgraded importance.  The most useful feature for teaching new students - aside from the motivation gained by the unique & attractive shape - is the unprecedented logic of integration of the Rare Earth and Transition elements, usually found in a remote location on standard charts.

 

The s- and p-block tube is in the rear, with the transition metal loop coming off to the right and the rare earth metal loop forward.
The clear connection between the rare earth metals and the transition metals is shown here.

The spiral of the s- and p-block in the  Alexander Arrangement is clearly visible with the transition metal loop coming off to the left.

Topping the s- and p- block spiral is the Hydrogen crown, which demonstrates its relationship to many of the periodic groups.


The construction of the three-dimensional chart has been made relatively easy by professional design of the slots and tabs, by die cutting all that needs cutting, and providing instructions that are carefully tested and illustrated.



Assembled DeskTopper

The Acclaimed and Affordable periodic table that obeys the Periodic Law!

The DeskTopper is a new, color, complete Alexander Arrangement, assembled in minutes, a new and correct way of seeing and communicating the realities of the Periodic Table.  It is is printed in full color on heavy card stock.  Element data is contained in boxes that are over three quarters of an inch by a half an inch on colors based on those of the standard Sargent-Welch periodic table.  The three segments are die cut for easy removal from the background, and slots are pre-cut for color coded tabs.  Very complete instructions are provided (in the event assembly is not as intuitive as we intended).  The DeskTopper is four and three quarters inches at its highest point.


DeskTopper Kit

    $14.95  The DeskTopper


The Display Version of the Alexander Arrangement of the Elements is laminated on 25"x 38" index card stock, black on white, and die cut for easy assembly into 3-D. A second periodic table of the same size, a laminated poster with aluminum rails top and bottom is printed flat, for hanging, and is packaged with the 3-D unit. Each of the Display Arrangements carries the following basic element data in their boxes; atomic number, element name, chemical symbol, and atomic weight.  Instructions are included to prepare the constructed 3-D Arrangement for hanging.

When completed, the Student version of the AAE looks similar to the picture above
The Student Version, contains (12) hands-on periodic charts (with atomic numbers only) printed in black on white 11"x 17" index stock, die-cut for separation and assembly into a 3-D unit. The surface will accept color and lettering for completion in a selection of formats by teacher or students.  Each chart carries only the atomic number in each of the boxes, entry of other data as well as coloring to illustrate groupings is part of the participation activity of the student. Also, an instructor might use several of the Arrangements to illustrate some different types of element groupings.  The construction of the three-dimensional chart has been made relatively easy by design of the slots and tabs, by die-cutting all that needs cutting, and providing instructions that are carefully tested and illustrated. Instructions are also included to prepare the constructed 3-D Arrangement for hanging.

Coloring the families of the periodic table is one of the learning steps for the Student version of the AAE
