What is the electronic configuration of Fe(II) ion?
Mar 22, 2015 · The electronic configuration of Fe is [Ar] 3dX6 4sX2 [A r] 3 d X 6 4 s X 2. So after removing two electrons the configuration becomes: [Ar] 3dX6 [A r] 3 d X 6 But why can't the …
Differences between Fe3+ and Fe2+ - Chemistry Stack Exchange
Dec 9, 2015 · I would like to know the differences between Fe3+ and Fe2+ ions. I'm guessing they must differ in reactivity but I'm not sure how. Also, is there a way that we can observed the differences
Why do iron (II) ions and chromium have different electronic ...
Aug 30, 2015 · For starters, it isn’t nearly as simple as it is usually put in chemistry classes to explain chromium’s ground state electron configuration. Cr(0) C r (0) and Fe(II) F e (I I) have the same …
biochemistry - Why does the structure of haemoglobin change when …
May 15, 2018 · It is said that FeX2+ F e X 2 + can bind oxygen while FeX3+ F e X 3 + cannot. Why is that so? FeX3+ F e X 3 + has an extra electron, it could bind more easily to the oxygen. And how …

Sep 16, 2015 · I heard that Fe(III) F e (I I I) is more common than Fe(II) F e (I I) but I've not heard a very clear explanation. Could someone please explain this incorporating electron configurations in their …
Is there an iron–iron bond in diiron nonacarbonyl?
Aug 27, 2017 · Diiron nonacarbonyl, $\\ce{[Fe2(CO)9]}$, is often depicted with an Fe–Fe bond as shown at the left-hand side: The Fe—Fe bond is usually invoked in order to (1) explain the observed …
Why is Cr(2+) a stronger reducing agent than Fe(2+) in water?
According to me, FeX2+ F e X 2 + should be a better reducing agent because FeX2+ F e X 2 + - after being oxidized - will attain a stable dX5 d X 5 configuration, whereas CrX2+ C r X 2 + will attain a …
