Mendeleev's 1904 Periodic Table

Mendeleev periodic table formulation from 1904.

This formulation was prepared to go with Mendeleev's article predicting that the ether (aether) would be found at the head of group zero in period zero. Also that dashes are left for six elements between H and He.

The predicted elements eka-boron (scandium), eka-aluminium (gallium) & eka-silicon (germanium) are present but the radioactive eka-manganese (technetium) is not. Also, the noble gas elements are on the left hand side of the formulation:

Werner's Periodic Table Arrangement

Above from Quam & Quam's 1934 review paper.pdf and below from Eric Scerri.

Eric comments that the interesting features are:

  • A remarkably modern looking formulation in that it separates not only the transition metals but also the rare earths into separate blocks to give what we would now call a "long-form 32 column table". Except Werner guessed wrong as to how many rare earths exist, with the result that he shows 33 groups.
  • This formulation is also interesting for showing an element between H and He and two elements before H.
  • Werner computed the average gaps between atomic weights for the second through the fifth periods as 1.85, 2.4, 2.47 and 2.5, respectively.
  • From this he extrapolated the gap for the first period as 1.5, which coincidentally was also half the difference between the atomic weights of H and He. Werner thus predicted a new element with atomic weight 2.5.
  • Moseley's work of 1913 showed there were no elements before H and none between H and He.

Moseley's Periodic Law

Henry Moseley (1887-1915) subjected known elements to x-rays and was able to derive a relationship between x-ray frequency and number of protons.

From Scientific American:

"It was the clever young English physicist, Moseley, who discovered that the atomic number for each element was the number of external electrons in the atom.

"With this discovery came a law concerning the X-ray lines of any element in an X-ray target.

"Moseley's law states that the wavelength of these lines is inversely proportional to the square of the atomic number of the element. Therefore, if we know the atomic number of the element we are looking for, we can predict the wavelength of· certain lines in its X-ray spectrum.

"If we set up our X-ray spectrograph so as to catch these lines where we expect them to fall, then, if the element is present in the target which we have chosen to use in our X-ray tube, we should know it. This provides one good way to identify difficult elements, but it is well to have another to use as a check. One of the best of these, and one which is almost as sensi- tive as the X-ray method, is that of positive.ray analysis."

Philip Stewart says:

"I believe that Hackh's 1914 spiral is of special interest it is the first spiral to take account of Mosley's atomic numbers, and the first to show successively larger pairs of coils. It is also interesting because H stands alone in the centre. I have only seen Mazurs' redrawn (as usual!) version, but Mazurs gives SciAm Supplement 1919 as one reference."

Deming Periodic Table

H.G. Deming used the long periodic table in his textbook General Chemistry, which appeared in the USA for the first time in 1923 (Wiley), and designated the first two and the last five Main Groups with the notation "A", and the intervening Transition Groups with the notation "B".

The numeration was chosen so that the characteristic oxides of the B groups would correspond to those of the A groups. The iron, cobalt, and nickel groups were designated neither A nor B. The Noble Gas Group was originally attached (by Ueming) to the left side of the periodic table. The group was later switched to the right side and usually labeled as Group VlllA.

This version of the periodic table was distributed for many years by the Sargent-Welch Scientific Company, Skokie, Illinois, USA.:

Andreas von Antropoff's Periodic Table

The Andreas von Antropoff periodic table, restored by Philip Stewart on the basis of the article 'Eine neue Form des periodischen Systems der Elementen'. Zeitschrift für angewandte Chemie 39, pp. 722-725, 1926:

This formulation has a satisfying balance compared to most other tables and was the most popular wall-chart in German schools for many years but quickly disappeared after von Antropoff was disgraced in 1945 for his Nazi activities: he presided over the raising of the swastika over Bonn University in 1933. But he put science above politics and was a stout defender of Einstein's theories.

A recently restored wall version of the von Antropoff formulation from the University of Barcelona, origionally painted in 1934 (thanks to Philip Stewart & Claudi Mans):

 

Perhaps it was the disgrace of von Antropoff which led Linus Pauling to borrow his design, without acknowledgement, for his 1949 book, General Chemistry (and subsequently in later editions of The Chemical Bond).

Riesenfeld Periodic Table

From here, using Google Translate:

This table is from the book "Practical Inorganic Chemistry" Publisher EH Riesenfeld Labor, Barcelona (1950). It is a reprint of the second edition (1943) which in turn is a translation of a German edition, its seventh edition in 1928. This suggests that Riesenfeld is himself the author of it.

It is a pre-Seaborg table in the sense that the actinides are known throughout the period July. It also does not include the Tc since it was discovered in 1937. These facts support the dating of the table. But the most interesting thing about it is that to make the separation between subgroups and major groups Be cut after the first period and after the Al in the second. Which leaves isolated in group B without any element 2b below it:

Nekrasov Periodic Table

From here, using Google Translate:

The shape of the table is presented by Bohr effect of considering the properties of the elements as simple substances and for reactions to occur with the intervention of such substances. But for the study of compounds and reactions that occur between them, the key factor is the electron configurations of atoms in states of valence to them on the given compounds.

It follows that a more complete picture of the periodic table would be when you take into account the peculiarities of atoms in both its neutral state and in all its particular valence states. This is the proposal of Boris Nekrasov, a member of the Academy of Sciences in Moscow.

Nekrasov distinguishes three types of analogies between elements Total analogs are those in which the analogy is shown in all its valence, all analogs compared to the valence valences except for the group corresponding to the number that can be called characteristic and analogous to the valence characteristic .

Thus, in the table shown here distinguish the elements entirely analogous joined by continuous lines, such as Na and K.

Those analogies in all except the characteristic valences joined by dotted lines. This is the case of Na and Cu in both cases if you lose an electron (valence feature) your setup is different. In the first case is 8 (1s2, 2P6) and the second 18 (3s2, 3p6, 3d10).

Lastly presenting exclusively analogies carcetrística valence are connected with dashed lines. This is the case both S and Cr +6 elements have their valence electron configuration similar in the last layer 8 (2s2, 2p6) for the S and 8 (3s2, 3p6) for Cr.

The date 1930 is an educated guess:

Paneth's Table

Published by Paneth in 1942 in an article in Nature in which he suggests that newly discovered elements such as Z = 43 should be given names by their discoverers. The other highlighted elements (below) had also not yet been named.

Element 43 had been discovered 9 years earlier but had not been given an official name because there was reluctance to consider synthetic elements on the same footing as naturally occurring ones. This changed as a result of Paneth's article.
