The electron configuration of a neutral magnesium atom is: 1s2 2s2 2p6 3s2 or in shorthand [Ne] 3s2. Aluminum (atomic number 13), with 13 electrons and the electron configuration [Ne]3s 2 3p 1, is analogous to its family member boron, [He]2s 2 2p 1. The electron configuration of an atom is 1s 2 2s 2 2p 6. Question: What Is The Electron Configuration For A Magnesium Ion, Mg? Magnesium is a chemical element with the symbol Mg and atomic number 12. Potassium. Thank You . Tags: Question 14 . 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. 1s 2 2s 2 2p 6 3s 1. Magnesium. There are 118 elements in the periodic table. In magnesium atom K shell contains 2 electrons and L shell contains 8 electrons and M shell contains 2 electrons which are valence electrons. Mg+2 is an ion that loses two electrons from its highest energy level, 3s. 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.
