Circular Periodic Table

From the accompanying text in the magazine

The irregular spiral above is a systematic arrangement of the 92 natural elements, the four new elements so far created by man and eight more elements which is theoretically possible to create… It is on the basis of this number [of electrons] that the elements are arranged in sequence: after hydrogen, with its single electron, come helium with two, lithium with three, beryllium with four and so on around the spiral… The table is so organised that elements whose chemistry is almost identical are grouped together in blocks or connected by solid arrows (al the inert gases – helium, neon, etc. – fall in the single gray block at the left).
