Its formation is not a singular event but a fundamental transformation dictated by the loss of electrons, a process driven by the atom's inherent desire to achieve a stable electronic configuration. Magnesium has a relatively low first ionization energy compared to elements like neon or oxygen, which facilitates the loss of the first electron.

When this occurs, the remaining 10 electrons reconfigure to match the electron configuration of neon (1s 2 2s 2 2p 6 ). The electron configuration is 1s 2 2s 2 2p 6 3s 2.
However, the overall process is driven by the large release of lattice energy or hydration energy when the resulting ions interact with other species. At the heart of countless chemical reactions and biological processes lies the unassuming magnesium ion, a divalent cation denoted as Mg 2+.
From Neutral Atom to Charged Ion: The Electron Loss Transformation
Energy Dynamics: Ionization Energy The process of removing electrons to form cations requires energy, and this is quantified by ionization energy. With an atomic number of 12, a standard magnesium atom possesses 12 protons in its nucleus and 12 electrons arranged in specific energy levels.
