Toma's Periodic Tables

Henrique E. Toma writes:

"I will be delighted if I could have a chance to contribute for the fantastic moment expressed by 2019 IYPT.

"I am senior Professor of Chemistry at the University of São Paulo, and great Periodic Table enthusiast since the beginning of my career about 50 years ago. This interest actually came from my supervisor and mentor, Professor Henry Taube (Nobel Prize, 1983), who taught me the beauty of the elements."

"As an inorganic chemist, I have been collecting the elements and minerals for a long time, and I built up the Periodic Table with the real elements shown below. It is one of the attractions of the campus, and has been reported in many publications1. It was visited by colleagues from IUPAC, including the President. I wouldn't be surprised if it inspired IUPAC the similar Table exposed in Paris, this year. The difference is that our table is that it also places the typical minerals together with the elements, and I believe that this is very important aspect for teaching and discussing the history behind them:

"Next, is my personal version of the IUPAC Periodic Table, shown in Figure 2, with the isotopes distributed in a column right to the element symbol. This Table is very practical, and particularly useful when you are dealing with mass spectrometry or isotopes. It is in my book of Elements2.

"Another is the Periodic Table of the Elements for Life, with the essential elements and abundance expressed by colors, including those used in medicine. This Table will be changing with the progress of Bioinorganic Chemistry, and is in my book of Bioinorganic Chemistry3.

"Finally, I have adapted the periodic table of elemental sustainability, using the colors to call attention for this issue. In this form, it is can be more easily understood by the public. Elemental Sustainability is a very important issue, as discussed in Green Chemistry Journal4.
