Here are the essential concepts you must grasp in order to answer the question correctly.
Ion Formation
Ion formation occurs when atoms gain or lose electrons to achieve a stable electron configuration, often resembling the nearest noble gas. Metals typically lose electrons to form positively charged cations, while nonmetals gain electrons to form negatively charged anions.

Magnesium's Position in the Periodic Table
Magnesium (Mg) is located in Group 2 of the periodic table, which consists of alkaline earth metals. These elements have two valence electrons, and they tend to lose these electrons during chemical reactions, resulting in a +2 charge for the ion formed.

Charge of Ions
The charge of an ion is determined by the difference between the number of protons and electrons. For magnesium, losing two electrons results in a net positive charge of +2, leading to the formation of the Mg²⁺ ion, which is common in various compounds.
