WebFrom this perspective, the reaction between magnesium and oxygen is written as follows. 2 Mg + O 2 2 [Mg 2+ ] [O 2-] In the course of this reaction, each magnesium atom loses two electrons to form an Mg 2+ ion. Mg Mg 2+ + 2 e - And, each O 2 molecule gains four electrons to form a pair of O 2- ions. O 2 + 4 e - 2 O 2- WebJul 18, 2024 · The charge on an atom is related to its valence electrons or oxidation state. An atom of an element is most stable when its outer electron shell is completely filled or half-filled. The most common charges are based on maximum stability for the atom. However, other charges are possible. shanghai zhao fan info tech co. ltd
