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- WebNov 9, 2024 · How does oxygen O form an ion? Oxygen, O. Oxygen is in Group 6. It has six electrons in its outer shell. It gains two electrons from one or two other atoms in reactions, forming an oxide ion, O 2-. What ions make up oxygen? Oxygen is present as the oxide ion, O2-, in the crystalline structure of solid metallic oxides such as calcium oxide, CaO.
