Understanding Valence Numbers

Valence numbers, also known as oxidation states, refer to the number of electrons an atom can gain, lose, or share to form a chemical bond. For magnesium, the valence number is particularly important because it determines how magnesium interacts with other elements. Magnesium typically has a valence number of +2, meaning it tends to lose two electrons to achieve a stable electron configuration.
