Romanoff's System

From Revue Scientifique 1934, V. Romanoff's paper (pages 661–665) Le Système Périodique de Mendéléeff Par Représentation Graphique.

Dr. Erik Strub writes:

"The article's Fig. 1 is the first [formulation] (to my knowledge) which contains a "classical" representation of the periodic system in which an Actinoide series is placed beneath the Lanthanoides and not beneath the d block elements:

Romanoff's System of 1934 (from van Spronsen):

Leningrad Monument To The Periodic Table

Leningrad monument to the periodic table, located near to the main chamber of weights and measures, 1934 (from van Spronsen):

From Wikipedia:

Brazilian Version of The Hubbard Periodic Chart Of The Atoms

A Brazilian Version of the American classic Henry Hubbard Periodic Chart Of The Atoms from a lecture theater in Rio, rediscovered by Martyn Poliakoff of PeriodicVideos.com and The University of Nottingham. From the early 1930s:

• Ma – Masurium (43) Disputed claim to discovery of technetium.
• Cb – Columbium (41) Former name of niobium
• Ab – Alabamine (85) Discredited claim to discovery of astatine.
• Il – Illinium (61) Discredited also
• Sa – Samarium (62) Current symbol is Sm
• Sp – Spectrium (70) Suggested name for ytterbium
• Cb – Columbium (41) Former name of niobium (also called Pelopium)

The current Sargent Welch version of the Henry Hubbard Periodic Table:

White's Periodic Table

The periodic table of White shows the normal state electronic configurations, from H.E. White. Introduction to Atomic Spectra. New York: McGraw-Hill, 1934,
p. 85, Table 5.4..

Helium is clearly associated with H, and placed above Be in accord with the s² electron configuration of the free atom.
