Mn Electron Configuration
What is the composition of 11 electrons for Mn + 4 ion?
1s2 2s2 2p6 3s2 3p6 4s2 3d1
Okay, Mn has 25 electrons, but you have +4 ions, which means you've lost 4 electrons, so your electron composition should be 21 electrons. In the indicator, the first number is the energy level, the letter is where the electrons are, and the number S is the number of electrons.
Now look at the IC table and follow the electron configuration. You will see that it shows you the continuity of where the table ike resides according to the number of electrons present. You will end up in the 21 sc element because it has 21 electrons.
Well, first here is the MLLL electronic configuration:
Mn = [Ar] 4s 2 3d 5 If the manganese ion loses electrons (to make Mn4 +), it first loses the electrons to the valence (4s2 instead of 3d5) and then to the next higher energy level (3d5 here).
Therefore, the order of electrons for Mn4 + is LL
Mn4 + = [wind] 3d 3
(Since 4s2 loses both electrons, it does not need to be inserted into the electron formation)
