Magnesium Electron Configuration: Magnesium (Mg) is an essential chemical element with the symbol Mg and atomic number 12. It belongs to Group 2 (alkaline earth metals) on the periodic table and is a lightweight, silvery-gray metal known for its strength, corrosion resistance, and excellent conductivity. Magnesium plays a vital role in industries such as aerospace, automotive manufacturing, electronics, and even human health. If you’re searching for the electron configuration of magnesium, this periodic table guide provides a simple and accurate explanation.
Magnesium Electron Configuration
The electron configuration of Mg is 1s² 2s² 2p⁶ 3s², while its noble gas shorthand electron configuration is [Ne] 3s². Since magnesium has 12 electrons, they are arranged across three energy levels, with two valence electrons in the 3s orbital. These two outermost electrons explain why magnesium commonly forms a +2 oxidation state (Mg²⁺) and shares many chemical properties with other alkaline earth metals like beryllium and calcium.
