1940s – Stedman's 3D Periodic Table

3D Periodic Table

Dr. Don Stedman from the National Research Council Canada designed this 3-D periodic table in the 1940s. Stedman considered many factors and characteristics of the elements as he designed his models. While in this model all the usual groups of elements are found, changes from one group to another are also represented, and their origins are more easily understood. Stedman believed that his model gave more insight into “the orderly development and classification of the elements.”
