The orbital diagram of magnesium (Mg) shown below:
The electrons in an atom are depicted in orbital diagrams in visual form. For creating orbital diagrams, three guidelines are helpful. Each electron resides in the orbital with the lowest energy, in accordance with the Auf Bau Principle. There may be only two electrons in a single orbital, according to the Pauli Exclusion Principle.
An orbital diagram, often known as an orbital box diagram, is a visual representation of an atom's electron arrangement. The electrons occupying the orbitals are shown as arrows (or half-arrows).
Mg have 12 electrons in the neutral atom
so the electronic configuration of the Mg is: 1s² 2s² 2p⁶ 3s²
orbital diagram is as follows:
