What is the electron configuration for a magnesium ion, Mg? 10. Question: What Is The Electron Configuration For A Magnesium Ion, Mg? Each element has a unique atomic structure that is influenced by its electronic configuration, which is the distribution of electrons across different orbitals of an atom. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure. The electron configuration of an atom is 1s 2 2s 2 2p 6. Tags: Question 14 . This problem has been solved! In magnesium atom K shell contains 2 electrons and L shell contains 8 electrons and M shell contains 2 electrons which are valence electrons. For example, lithium forms Li +, with the 1s 2 configuration, magnesium forms Mg 2+, with the 2s 2 2p 6 configuration for its highest energy electrons, and chlorine forms Cl-, with the 3s 2 3p 6 configuration.
