The edits by SmokeFoot were made to remove a lot of the descriptive language used. SmokeFoot commented "Wikipedia is not a school essay. It is a compilation of facts." The negative numbers refer to the amount of bytes removed from the page meaning stuff was removed. These were necessary edits to make because Wikipedia should use neutral language and only state information. The section also gave extra information not directly relevant to the article.

Wikipedia “Iron–sulfur cluster” article: Talk page discussion of Dec 4th / 5th 2018 edits:

Hello,

I hoping to contribute, my knowledge to this article by discussing the strength, covalency and electron transfer effects. Ninja Recs (talk) 01:00, 12 October 2018 (UTC)

I think SmokeFoot's edit to line 26 on Dec.3rd 2018 made it better because it was more concise. The November 2019 paragraph addition was a good improvement to the introduction. It gave more information on how hemoglobin works and was explained well. This addition to the article is still currently there. I do not think there is enough useful discussion on the talk page. There are some unanswered questions or questions that have unsatisfactory answers.

Blue Copper Protein Entatic State

Cu2+ complexes normally have slow transfer rates. An example is the Cu2+/+ aquo, which is 5 x 10-7 M-1.sec-1 compared to the blue copper protein which is 1ms-01μs. The high energy barrier is because of the Jahn-Teller Distortion of the Cu2+. Upon electron transfer the oxidized Cu2+ state at the blue copper protein active site will be minimized because the Jahn Teller effect is minimized. The distorted geometry prevents Jahn-Teller distortion. The orbital degeneracy is removed due to the asymmetric ligand field. The asymmetric ligand field is caused by the strong cysteine ligand which is short, at equatorial position and the weak methionine ligand which is longer at axial position. In Figure 2, the energy level diagram shows three different relevant geometries and their d-orbital splitting and the Jahn-Teller effect is shown in blue. (i) shows the tetrahedral geometry energy level diagram with a that is degenerate. The tetrahedral structure can undergo Jahn-Teller distortion because of the degenerate orbitals. ii) shows the C3v symmetric geometry energy level splitting diagram with an 2E ground state that is degenerate. The C3v geometry was formed by the elongated methionine thioether bond at the reduced site. The unpaired electrons lead to the Jahn-Teller effect. (iii) shows the ground state energy level splitting diagram of the Cs geometry with a longer thioester bond and a subsequently shorter thiolate bond. This is the proper geometry of the blue copper protein. The energy diagram shows that the asymmetry of the short Cu-S(Cys) bond and the highly distorted Cu-L bond angles causes the degeneracy of the orbitals to be removed and thereby removing the Jahn-Teller effect, which is due to the weak donor at an Cu-S(Met) and strong donor at Cu-S(Met).
