Om de kemiska grundämnenas periodiska system.
Stockholm, P. A. Norstedt & Söner, 1885. 8vo. Uncut, unopened in the original printed wrappers. In ""K. Scenska Vet.-Akad. Handlingar. Band 10. No. 2"". Fine and clean. 31 pp, + 2 plates.
First appearance of Rydberg's important paper on the periodic table in which he intruduced atomic numbers and made his famous conclusion: ""The discovery of the periodic system have made it impossible to consider the chemical elements as simple and independent, and it has thus become a matter of great interest to searching explain the context between them. [...] And it would certainly confirm that the differences [between the atomic weights] periodically change, one must assume that the atomic weights themselves grow after a periodic law when it progresses in the system, and thus are to be regarded as periodic functions of their number. ""Rydberg’s most significant scientific contributions were to spectroscopy: but his involvement with spectra had its origin in his interest in the periodic system of the elements, an interest that endured throughout his professional life. His earliest published papers in physics dealt with the periodic table. In the introduction to his major work on spectra (1890), he stated that he considered it only a part of a broader investigation, the goal of which was to achieve amore exact knowledge of the nature and constitution of the chemical and physical properties of the elements. He held that the effective force between atoms must be a periodic function of their atomic weights and that the periodic motions of the atoms, which presumably gave rise to the spectral lines and were dependment on the effective force, thus might be a fruitful study leading to a better knowledge of the mechanics, nature, and structure of atoms and molecules and to a deeper understanding of the periodic system of the other physical and chemical properties of the elements. In line with contemporary conceptions, Rydberg’s view was that each individual line spectrum was the product of a single fundamental system of vibrations."" (DSB)

Elektron der erste Grundstoff.
Lund, Håkan Olssons Buckdruckerei, 1906. Lex8vo. Orig. printed wrappers. One of Rydberg's own copies with ""Ueberreicht vom Verfasser"" printed on frontwrapper. 30 pp., 2 large folded tables (the periodic system).
First edition of important revison of the periodic system in one the author's presentation copies (""Ueberreicht vom verfasser).""Rydberg’s study of the periodic properties of the elements led him in 1897 to suggest that certain characteristics of the elements could be more simply organized by using an atomic number instead of the atomic weights. This atomic number was to be identified with the ordinal index of the element in the periodic table. In 1906 Rydberg stated for the first time (the paper offered) that 2, 8, and 18 (that is, 2n2, where n= 1,2,3) represented the number of elements in the early periods of the system. In 1913 he went further, correcting an earlier error about the number of rare earths from 36 to 32, thus allowing the n = 4 group to be included in the pattern."" (DSB).

Untersuchungen über das System der Grundstoffe.
Lund & Leipzig, Gleerup & Harrassowitz, 1913. 4to. In the original printed wrappers. With author's presentation inscription to top of front wrapper: ""Från vännen forf."" Fine and clean. 41 pp.
First appearance of Rydberg's important paper in which continued his revision of the periodic system. Here he ascribed two hypothetical new elements which he called nebulium and coronium and came up with the formula 2p*2 (p integer) which Sommerfeld called ""cabbalistic"" in his book ""Atombau und Spektrallinien"".
Beiträge zur Kenntniss der Linienspectren I-III + IV (2 papers).
Leipzig, Barth, 1893-94 Both in orig. printed yellow wrappers. 2 Offprints from Annalen der Physik und Chemie, Neue Folge. Band 50. and Band 52. Separat-Abdrucke. Ueberreicht vom Verfasser. pp. (625-)638 + (119-)131. Clean and fine.
First printing of these main papers in spectroscopy of the elements, where Rydberg predicts lines of definite wave-lenghts in the spectrum of one or the other element.
