Talk:Iron/Archive 3

Edits of today
I removed the following set of statements that were redundant or appear to be incorrect: It is the most important transition metal in all living organisms. Iron-proteins are found in all living organisms: archaeans, bacteria and eukaryotes, including humans. For example, the color of blood is due to hemoglobin, an iron-containing protein. As illustrated by hemoglobin, iron is often bound to cofactors, such as hemes, which are non-protein compounds, often involving metal ions, that are required for a protein's biological activity to happen. Iron is a necessary trace element found in nearly all living organisms. Iron-containing enzymes and proteins, often containing heme prosthetic groups, participate in many biological oxidations and in transport. I plan to delete this note in a few days. --Smokefoot (talk) 02:20, 17 February 2018 (UTC)

A bit too much ferrocene...

Coordination complex vs organometallic compound
Does the article adequately explain the difference? Is ferrocyanide "organometallic"? --Jorge Stolfi (talk) 18:56, 1 April 2019 (UTC)

BHmax for iron?

 * Warning
 * Basic collegiate electromagnetics here: not familiar with remnance, gauss, etc.

I see a BHmax value listed for various compositions of Alnico, NIB, and CoSm magnets, roughly describing what laypeople think of as the "strength" of a magnet. (It's not, really, it's basically the energy-per-unit-volume that can be put into a magnet of that material) That said, it's relevant to the efficiency of motors and generators that use that kind of magnet to attract or excite the coils in the device: that's why electric cars are more practical today with NIB magnets than they were in yesteryear with iron bar magnets.

Is there a value for a simple iron bar magnet to compare the values to other kinds of (ferrite, NIB, etc) magnets? If so, can you please work that into the section on magnetics?

Thank you,

History of iron
"Humans started to dominate [sic] that process in Eurasia only about 2000 BCE ..." -- "dominate" is the wrong word; I believe "develop" may have been intended.73.95.132.206 (talk) 04:51, 14 August 2019 (UTC)
 * It can be "to have or exert mastery" according to Merriam-Webster. Not saying it shouldn't change, it just doesn't seem wrong to me. BernardoSulzbach (talk) 16:40, 14 August 2019 (UTC)

"Iron ores are among the most abundant metals"
I really like this project, where commoners and professional can work side by side for the benefit of mankind. However, sometimes it clearly shows that the plebs does not cope with the pros. To make it clear; iron ore is an oxide, and that is not a metal, read a little bit here: Oxidation state, or better take a University degree in real matters, User:Zefr, you might have a doctorate in philosophy, but that is to no avail when it comes to real matters.

 * So Zefr realized the difference between an oxide and a metal! Good learning, because there is a difference, which migth be obscure to common people. Eivindgh (talk) 23:56, 1 September 2019 (UTC)

Under "Origin and Occurrence in Nature">"Metallic Iron", I'm requesting the sentence: "The other terrestrial planets (Mercury, Venus, and Mars) as well as the Moon and are believed to have a metallic core consisting mostly of iron." be changed to: "The other terrestrial planets (Mercury, Venus, and Mars) as well as the Moon are believed to have a metallic core consisting mostly of iron." since "the moon and are" is incorrect grammar.

Earth’s Crust
The following paragraph really doesn’t make sense:

“While iron is the most abundant element on Earth, it accounts for only 5% of the Earth's crust; thus being only the fourth most abundant element, after oxygen, silicon, and aluminium.[31]”

Perhaps the intention was to state that iron is the most abundant element by weight? — Preceding unsigned comment added by 5.30.179.46 (talk) 21:19, 13 May 2020 (UTC)

Semi-protected edit request for Iron page on 22 November 2020

I suggest the following written below to be added to the "Iron" page under a new section heading of "Iron's Role in Marine Systems". The text and sources under this section would be the following:

Iron plays an essential role in marine systems and can act as a limiting nutrient for planktonic activity. Because of this, too much of a decrease in iron may lead to a decrease in growth rates in phytoplanktonic organisms such as diatoms. Iron can also be oxidized by marine microbes under conditions that are high in iron and low in oxygen.

Iron can enter marine systems through adjoining rivers and directly from the atmosphere. Once iron enters the ocean, it can be distributed throughout the water column through ocean mixing and through recycling on the cellular level. In the arctic, sea ice plays a major role in the store and distribution of iron in the ocean, depleting oceanic iron as it freezes in the winter and releasing it back into the water when thawing occurs in the summer. The iron cycle can fluctuate the forms of iron from aqueous to particle forms altering the availability of iron to primary producers. Increased light and warmth increases the amount of iron that is in forms that are usable by primary producers. Bluebelle1811 (talk) 20:48, 22 November 2020 (UTC)

Iron at peak of binding energy curve
SEEK to add this fact about iron,, does not seem to be in article yet... Factoid to add to article on iron --- The buildup of heavier elements in the nuclear fusion processes in stars is limited to elements below iron..

readers benefit knowing iron very special in the science of fusion

thank u .. . binding energy curve. ..very cool... Iron is this min in a fusion fission Function  just learned that about Nature , wiki full of amazing facts..amazing we apes figured this... https://www.youtube.com/watch?v=yOiABZM7wTU   good day Knowledge357111317 (talk) 02:33, 2 April 2021 (UTC)

FA nomination
Please follow the FA instructions before nominating. You aren't a major contributor to the article and made no effort to reach out to the major contributors before the nomination. In addition, this article does not stand a chance of passing FAC per WP:SNOW, there are major issues such as overuse of images and large quantities of uncited text.
