Ions fe2+
WebFe2+ Ground State Electron Configuration. When 2 electrons are removed from neutral fe atom fe2+ ion is formed. The ground state fe2+ electron configuration of fe2+ is 1s2 2s2 2p6 3s2 3p6 3d6. 2 electrons are removed from 4s orbital as it has higher energy than 3d orbital making the valance shell electronic configuration of fe2+ is 3d6. WebThe iron atoms exhibits Fe 2+ and Fe 3+ ions. The iron atom donates two electrons in the 4s orbital to form an iron ion (Fe 2+ ). Fe – 2e – → Fe 2+ Here, the electron configuration of iron ion (Fe 2+) is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 6. The iron atom donates two electrons in 4s orbital and an electron in 3d orbital to convert iron ion (Fe 3+ ).
