Période

1940s +

Canada

From acquisition proposal "From laboratory of National Research Council of Canada, one of Canada's foremost research establishments in number of scientific & technological areas. Model was developed by NRC scientist Dr. Don Stedman. In 1930s he expressed belief that there were more than 92 elements, an idea subsequently found to be correct."

Fonction

A 3D representation of the periodic table of the elements, consisting of cyclic spiral arrangement of elements. Hydrogen is at the apex and the series of elements is arranged in spiral, including the as yet undiscovered heavy elements of the 1940’s/50’s.

Technique

From acquisition proposal "According to Dr. Stedman (ref. 2), this arrangement has advantage of separating each type of element without ambiguity. It accommodates rare earth & viii groups as integral & significant part of orderly development of table. Opposing nature of electropostive & electro- negative elements is clearly shown."
