When a magnesium atom gains an electron in its energy shell, it becomes negatively charged and transforms into a magnesium anion (Mg²⁻). This process occurs because magnesium has three valence electrons and seeks to achieve a stable electron configuration. Gaining an electron allows it to fill its outer energy shell, but typically, magnesium tends to lose its valence electrons to form a cation (Mg²⁺) instead. Thus, while it is theoretically possible for magnesium to gain an electron, it is more common for it to lose electrons in chemical reactions.
The shorthand electron configuration of magnesium is [Ne]3s2.
The first electron affinity of magnesium is exothermic. This means that energy is released when a neutral magnesium atom gains an electron to form a magnesium ion.
Magnesium has three electron shells. The electron configuration is 2,8,2
Magnesium has 3 electron rings.
Magnesium has 3 electron shells.
It becomes a positively charged Magnesium ion.
The shorthand electron configuration of magnesium is [Ne]3s2.
The element magnesium has the same number of electron orbitals as sodium - both have three electron orbitals. Sodium and magnesium are in the same period on the periodic table, which means they have the same number of electron shells.
If you think to the electron configuration of magnesium this is: [Ne]3s2.
Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.

A magnesium atom has 12 electrons arranged in 3 shells. The electron configuration of magnesium is 2-8-2, indicating that it has 2 electrons in the first shell, 8 in the second shell, and 2 in the third shell.
