# paramagnetism vs. dimagnetism

this was a question for my chem class- and for some reason the answer was the last option. Why isn't it $\ce{Mn}$ which has the most unpaired electrons?

Which of the following species would you expect to be most paramagnetic?
1. $\ce{Mn}$
2. $\ce{Mn^2+}$
3. $\ce{Fe^3+}$
4. Both $\ce{Mn^2+}$ and $\ce{Fe^3+}$ are the same and more paramagnetic than $\ce{Mn}$
5. All have the same paramagnetism.

$Mn :: [Ar]3d^54s^2$
$Mn^{2+} :: [Ar] 3d^5$
$Fe :: [Ar]3d^64s^2$
$Fe^{3+} :: [Ar] 3d^5$
