To determine its electron configuration, we begin with the neutral iron atom’s electron configuration and then adjust it based on the loss of electrons.
Explanation of the filling of orbitals according to the Aufbau principle
The Aufbau principle states that electrons fill orbitals in order of increasing energy. This means that lower energy orbitals are filled before higher energy orbitals. In the case of Fe2+, the electron configuration is determined by following the Aufbau principle.
Starting with the ground state of the iron atom, the electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d6. When two electrons are removed to form Fe2+, the last two electrons are removed from the 4s orbital. This means that the electron configuration of Fe2+ is 1s2 2s2 2p6 3s2 3p6 3d6.
The 3d orbital is not completely filled because the energy difference between the 3d and 4s orbitals allows for the removal of the 4s electrons before the 3d electrons. This is consistent with the Aufbau principle, where electrons fill orbitals with lower energy first.

The ground state electron configuration of the neutral iron atom, Fe, is 1s2 2s2 2p6 3s2 3p6 4s2 3d6. In the ground state, the orbitals are filled starting from the lowest energy level (1s) and progressively filling higher energy levels. The last electron to be filled in the ground state configuration is in the 3d orbital.
The 3d orbital can hold a maximum of 10 electrons, but in the ground state of neutral iron, only 6 of the 3d orbitals are occupied. This is because the 4s orbital, which has a lower energy, is filled before the 3d orbitals according to the Aufbau principle.
It is important to note that the ground state electron configuration of iron is stable and represents the most energetically favorable arrangement of electrons for the atom.
Detailed explanation of the removal of two electrons during the ionization of iron to form Fe2+
