How Is Na2O Formed?

Na2O is formed through the reaction of sodium metal with oxygen gas. This reaction is highly exothermic and releases a large amount of heat and light. The balanced chemical equation for this reaction is:

4 Na + O2 → 2 Na2O

In this reaction, each sodium atom loses one electron to form a sodium ion with a positive charge (Na+), while each oxygen atom gains two electrons to form an oxide ion with a negative charge (O2-). These ions then combine to form crystals of sodium oxide (Na2O) in a lattice arrangement.

It is important to note that this reaction should only be carried out under controlled conditions, as it can be dangerous due to the high reactivity of both sodium and oxygen. Proper safety precautions, such as protective gear and a well-ventilated area, should always be taken when working with these substances.
