Mn3+ Electron Configuration
Electronic configuration of Mn 3+ HELP !? 3
10 easy points. I've tried everything but I couldn't find it! I tried [Ar] 4s2 3d2, but your answer is wrong.
The electron configuration of Mn is: [Ar] 4s2 3d5
When Mn loses electrons to make the atom ion, 4s2 electrons go first, like this:
Mn2 + will have 3d5 [Ar] configuration.
Then 3d electrons pass so that Mn3 + has 3d4 [Ar] configuration.
This is [Ar] 4s2 3d5 for Mn.
For the Mn3 + ion, it could be [Ar] 3d4 because it has 3 fewer electrons.
