WRITE THE ELECTRONIC CONFIGURATION OF Fe3PLUS.
Electronic Configuration of Fe: Fe has 26 electrons, so its electronic configuration is -
1S2 2S2 2p6 3S2 3p6 3d6 4S2
But after removal of 3 electrons ( 2 from 4S and 1 from 3d), it will form Fe3+, which electronic configuration is -
1S2 2S2 2p6 3S2 3p6 3d5
