Semi-protected edit request on 15 March 2016[edit]

I'm just you everyday chemist. That means I don't do nuclear chem every day so I'm not super 100% on what Iron-54 decays into, but Double electron capture sounds right and that means the product would be Chromium-54. But this says it Double beta decay and I know thats not possible... let me check something. No I know I'm right I just found a paper about it. Any who this is what you got.

I this is what you should change it to. I've also changed the Decay energy to what the source says.

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

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.[1] Because of this, too much of a decrease in iron may lead to a decrease in growth rates in phytoplanktonic organisms such as diatoms.[2] Iron can also be oxidized by marine microbes under conditions that are high in iron and low in oxygen.[3] 

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.[4] 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. [5] The iron cycle can fluctuate the forms of iron from aqueous to particle forms altering the availability of iron to primary producers.[6] Increased light and warmth increases the amount of iron that is in forms that are usable by primary producers.[7] Bluebelle1811 (talk) 20:48, 22 November 2020 (UTC)[reply]
