"Periodic table" of combined elements

Click For Summary

Discussion Overview

The discussion centers on the idea of a comprehensive table or resource that relates combinations of elements, including simple substances, composite substances, and mixtures. Participants explore the feasibility and implications of cataloging all possible combinations of two or more atoms.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants propose the need for a table that relates combinations of elements, similar to the periodic table but focused on compounds and mixtures.
  • Others argue that the vast number of possible molecules makes it impractical to create such a comprehensive table, noting that millions of compounds have been described but many remain undocumented.
  • A participant highlights the complexity introduced by isotopes, suggesting that even for a single element like carbon, the number of potential combinations increases significantly.
  • It is mentioned that over 100 million molecules are registered at CAS, with a high rate of new registrations, indicating the dynamic nature of chemical discovery.
  • References to existing resources, such as the Handbooks by Gmelin and Beilstein, are provided as potential starting points for exploring chemical combinations.
  • One participant notes that while many molecules are registered, very few have significant utility, raising questions about the practical value of such a comprehensive catalog.

Areas of Agreement / Disagreement

Participants generally agree on the existence of a vast number of possible chemical combinations, but there is no consensus on the feasibility or utility of creating a comprehensive table of these combinations. Multiple competing views remain regarding the practicality and significance of such a resource.

Contextual Notes

Limitations include the vastness of possible combinations, the dynamic nature of chemical discovery, and the potential insignificance of many registered molecules. The discussion does not resolve the challenges of cataloging or the implications of isotopes on chemical properties.

The periodic table is globally known! But, it relates EACH element separately! Exist some table, some lists, some spreadsheet, etc, that relates the combinations between the elements and give us the information about each combination?

PS: for "combined elements" I want to say simples substance, composite substance, mixture, etc, I want to say ALL COMBINATIONS of TWO OR MORE atoms.

There is an unlimited amount of possible molecules. Hard to make a table out of it. Some millions have been described in more detail, even that doesn't fit. It also would not have the nice structure (periods, groups) the period table has.

There are millions of possible compounds which involve one element: carbon. It is doubtful that information is known on more than a handful of all the possible carbon molecules and their isomers. Not only that, but if your key element, say carbon in this instance, has multiple isotopes, then there will be even further combinations. While the chemical properties of elements composed of different isotopes don't vary, the same cannot be said of their physical properties.

I'm not sure how much storage space it would take to collect all of this information, assuming it was available.

More than 100 million molecules are registered at CAS, with 15000 new ones per day.

Have a look at the Handbooks by Gmelin and Beilstein.
