Mendeleev 150

Mendeleev 150 is the 4th International Conference on the Periodic Table. The event welcomed nearly 300 guests from over 30 countries and has become one of the key events of IUPAC's International Year of the Periodic Table.

Samanez's Binodic Periodic System, New Mathematical Paradigm Poster

Julio Antonio Gutierrez Samanez (Master's student in chemical engineering at the San Antonio Abad National University of Cusco, Peru) presented a poster at the 4th International Conference on the Periodic Table arranged by IUPAC, Saint Petersburg, Russian Federation, July 2019. See the high resolution .PDF file.

Hardware, Periodic Table of

From This Into That – by Jim Rosenau – comes a Periodic Table of Hardware that rather cleverly uses the usual element symbols:

  • H for hammer
  • He for hedge shears
  • Li for light bulb
  • etc.

Gorbunov and Filippov's Doubled Periodic Table

Gorbunov, A. I., Filippov, G. G.: Fine Structure of D. I. Mendeleev Periodic Table: secondary periodicity, early and late elements. Khim-ya Tekhnol. 11, 43–45 (2001). (in Russian)

Naum S. Imyanitov (Foundations of Chemistry) writes:

"The two-table design is of particular interest. Atoms with odd n+l are located in the upper table, and the ones with even n+l are placed in the bottom table (Tables 5). The elements are divided by a vertical line of symmetry to the early and late ones both in the upper and bottom tables. The advantage of Tables 5 is a clear demarcation into subsets, with each subset having its own separate place in the table. The drawback is directly related to this advantage: this table does not reflect the similarity between members of different subsets."

Bloomberg Businessweek: Why the Periodic Table of Elements Is More Important Than Ever

A Bloomberg Businessweek article on the chemical elements: Mendeleev's 150-year-old periodic table has become the menu for a world hungry for material benefits. (This story is from Bloomberg Businessweek's special issue The Elements.)

Where Mendeleev Was Wrong

A paper by Gábor Lente, Where Mendeleev was wrong: predicted elements that have never been found, from ChemTexts https://doi.org/10.1007/s40828-019-0092-5.

As is well known, Mendeleev sucessfully predicted the existance of several elements, but he was not always correct.
