2V^3+

3Ti^3+

4Fe^2+

​

Answer 1

Thus, we see that Fe2+ has the most unpaired electrons.

Answer 2

Which of the following has maximum number of unpaired electrons?

1Mg^2+

2V^3+

3Ti^3+

4Fe^2+

ANSWER:

4Fe^+2

$more \: about \: {fe}^{ + 2}$

• Fe2+ has paramagnetic properties

• Fe2+ has a pale green colour and turns violet when water is added to it.

• Iron(2+) is a divalent metal cation, an iron cation and a monoatomic dication. It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite, a mouse metabolite and a cofactor.
