Electronic Configuration of Magnesium Cation is explained here. The electronic configuration gives insight into how electrons are arranged or distributed across a molecule or atom. This arrangement is guided by the Aufbau principle, which states that electrons are filled into atomic orbitals in the increasing order of orbital energy level. According to the Aufbau principle, the available atomic orbitals with the lowest energy levels are occupied before those with higher energy levels. The number of electrons a shell or orbital can hold is based on ‘The Pauli exclusion principle. To understand any element’s electron configuration, we need first to have a basic understanding of the element and its properties.

MagnesiumMagnesium (Mg) is a naturally occurring Alkaline earth metal which belongs to group 2 (IIa) of the periodic table. It is silvery-white and lightweight. Its relative density is 1,74 and it’s density 1740 kg/m3 (0.063 lb/in3 or 108.6 lb/ft3). Its low weight is known as the best form of metal for forming mechanically resistant alloys. It is a stable and neutral element with no Positive charge ( +) or Negative charge (-) attached to it: the number of protons equals the number of electrons, which gives it its stable state. Its cation, Mg2+, is also essential in almost every biochemical metabolism.

Magnesium Cation Mg2+Magnesium cation (Mg2+) is, as stated above, is a cationic /less stable derivative of Mg formed after It gives up two of its valency or outer electrons from its electron shell or orbital.Electronic Configuration of Mg2+ tells us how many electrons are arranged in each shell of the Mg2+ atom and its shape. Mg2+ has an electronic configuration of 1s² 2s² 2p^6, i.e., has a total number of 10 electrons similar to that of a Noble gas
Order of Electron Arrangementn, The diagram below shows us how electrons are arranged around each shell or orbital and how many each shell can ca to understand this shift in quantum energy level or loss of electrons. The Aufbau Principle guides this principle of arrangementThe Periodic Table can also help us better understand this.
