The 3D PERIODIC TABLE

Before the three–dimensional periodic chart was re-introduced just before this century began, the conventional flat periodic table served generations of students and chemists well, and continues to do so. It provides the basis, not only for the introduction to chemistry, but a guide throughout the career of chemists, biologists, and teachers.
In spite of it's usefulness, difficulties in learning and using it have led to many efforts to improve the table. The elements have been placed in circles & spirals, duplicated elements, step–pyramids, trees, and target shapes with extensions. They have been formed into three–dimensional cubes, pyramids, stacks, even teardrops. Several have excelled the standard periodic table for accuracy and suitability in highly technical ways.

Falling partially within the spiral category, where discontinuities and displacements in the order of the elements have been overcome - but technically a helix - the 3D arrangement of the chemical elements developed by Roy Alexander, patented, and originally published in the mid–1990s retains all the positive features of the flat table except the ability to see all the elements all the time.

This modern periodic table is called the Alexander Arrangement of Elements, which features connecting the elements for easier understanding of element property trends clearly defining for beginning students the new conclusions regarding the dimensional aspects of hydrogen, atomic structure, and of nature itself.
You can find it on the above illustration, to the right and slightly above the center of the group.
