Answer 1

Oxygen is commonly a diatomic gas, meaning that it contains 2 atoms per molecule - hence a formula of O_2. Mg + O_2 -> MgO.

When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. A compound is a material in which atoms of different elements are bonded to one another. ... Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction.
