The alkaline earth metal magnesium (atomic number 12), with its 12 electrons in a [Ne]3s 2 configuration, is analogous to its family member beryllium, [He]2s 2.Both atoms have a filled s subshell outside their filled inner shells. Question: What Is The Electron Configuration For A Magnesium Ion, Mg? Mg+2 is an ion that loses two electrons from its highest energy level, 3s. 3. The electron configuration of a neutral magnesium atom is: 1s2 2s2 2p6 3s2 or in shorthand [Ne] 3s2. 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. 10. 6. https://www.periodic-table.org/magnesium-configuration-oxidation This document is highly rated by Class 9 students and has been viewed 2345 times. There are 118 elements in the periodic table. where as in magnesium ions the electronic configuration is 1s2 2s2 2p6 which attains Neon configuration. Tags: Question 2 . 30 seconds .
