Talk:Iron

Putting cost of the compounds per 100g will be useful for knowing it's worth and whether it's needed for a chemistry lab. There are variety of reagents ranging from commercial to L.R.. So I'm expecting Wikipedia team to put it asking with other properties of chemicals. Shivaramsenthil (talk) 13:13, 17 November 2023 (UTC) Shivaramsenthil (talk) 13:16, 17 November 2023 (UTC)

"Since addition of another alpha particle, resulting in ⁶⁰Zn, requires a great deal more energy": This needs clarification as the process is still exothermic. Should it be that the activation Energy is high? 14.52.231.91 (talk) 00:51, 16 August 2024 (UTC)

:The text is clarified. Beyond ⁵⁶Ni, photodisintegration becomes important, and it obstructs the alpha process. Nucleus hydro elemon (talk) 13:13, 16 August 2024 (UTC)

In the second paragraph of the article, it says smelting iron requires temperatures "about 500 °C (932 °F) higher than that required to smelt copper."

This most likely uses Wikipedia's standard temperature conversion formula (°F = (9/5)°C + 32). However, for a change in temperature, the formula is incorrect. It should be Δ°F = (9/5)Δ°C, so the text should read "about 500 °C (900 °F) higher". CopperChemist (talk) 03:36, 17 April 2025 (UTC)
