The Alexander Arrangement of Elements


The AAE is not an idea, it is a thing.
It is not a creation, or even an invention, but something I discovered - one in which I have co-discoverers; de Chancourtois, Courtines, and Gamov.
I don't know just how they all arrived at it, but I just stumbled upon it, and deserve no credit beyond recognizing it, and then preparing it to be a learning tool.

The science education value I hope for in my discovery is that it may one day be thought of in Science/Chemistry/Physics as the primary source of periodic tables as the globe has in Geography/Cartography/Roadmaps: the source of roadmaps and other projections.

In it is Simplicity, Correctness, Motivation, and Reality. ALL the parts connect exactly as Mendeleev specified. It has a place for all the data needed adjacent to all the data that should be there.

Alexander Arrangement Forever Periodic Table The Forever Periodic Table the very latest version, includes only those elements that are useful to the introduction of chemistry, and nothing ephemeral and/or confusing, so instructors can teach better and faster and students can learn easier. The immediate acceptance by students is augmented by the beautiful color photos of the elements by Theodore Gray and just the fact of it's being dimensional (13.75" high) and can be held in your hands.

The historical value is that the dimensionality and resulting full connectedness of all the elements and blocks is evidence that this form may well be THE actual element arrangement, of which all others are projections (think World globe = Mercator Projection.)

I am a museum science exhibit designer, a specialist in the design and development of educational devices, name of Roy Alexander, and I hope the Alexander Arrangement of Elements (AAE) helps eliminate the confusion and apparent inconsistencies in the flat table by being used in the classroom before exposure the the flattened chart.

Earlier Available Versions of the Alexander Arrangement

Alexander Arrangement Display version The resulting 3-D form (see photo at left, the Display version of the AAE) has three parts looping outwards from a relatively central point. The elements in Groups 0, Ia, IIa, IIIb, IVb, Vb, and VIIIb are in the narrowest and tallest part, which forms a tube in the upper part, topped by a `crown' of Hydrogen. From the lower part of this component the sides branch to a more lengthy loop showing groups IIIa, IVa, Va, VIa, VIIa, VIII, Ib, and IIb. From the lower half of this, a third, and longest loop protrudes, the f-block. First Loop of the AAE Printed as a flat sheet, it is easily assembled into a 3-D model by teacher or student. All element data, therefore, have a common plane so the elements can be traced by their electron numbers without changing direction or leaving the surface.

The successive period connections are achieved by a downward helix in the first of the three component loops (see photo at right, of the DeskTopper) This is the major factor in the U.S. Patent.

The DeskTopper is still available, a 4.75" high model that can be easily constructed by students in a classroom or on their own.

The most useful feature for teaching new students - aside from the motivation gained by the unique & attractive shape - is the significant integration of the Rare earth and Transition elements (see photo at left with student entered data on a no longer available Student Interactive version at left), usually found in a remote location on standard charts. Rare earths Loop During Glenn Seaborg's work on nuclear energy in the Manhattan Project during WWII he first placed the then new radioactive elements in a separate location. Before he died he had an Alexander Arrangement and determined that this 3-D method was now the correct way to show the Rare earths.

Including these three main improvements, the patented Alexander Arrangement of Elements is the first periodic table that is a learning aid in a natural, logical form of unprecedented clarity.
