The electron configuration of Fe2+ is 1s2 2s2 2p6 3s2 3p6 3d6. Fe2+ has lost two electrons from its outermost shell, leaving behind a filled d-subshell and an empty s-subshell.
Iron (Fe) is a transitional metallic element that can form various ions, including Fe2+. The 3rd energy level contains 8 electrons in the s and p orbitals. The electron configuration of Fe is 1s2 2s2 2p6 3s2 3p6 3d6 4s2.
However, when it loses two electrons to form Fe2+, the electron configuration becomes 1s2 2s2 2p6 3s2 3p6 3d6. The Fe2+ ion has a +2 charge, meaning it has two fewer electrons than neutral iron. This loss of electrons eliminates the 4s electrons, leaving the ion with a partially filled 3d sublevel. Understanding the electron configuration of Fe2+ is crucial in predicting its chemical and physical properties in various applications.
