Here's a breakdown of what happens:
* Zinc (Zn) is a metal that is relatively reactive.
* Oxygen (O2) is a highly reactive gas.
* When zinc is exposed to oxygen, the oxygen atoms react with the zinc atoms.
* Each zinc atom loses two electrons to form a zinc ion (Zn²⁺).
* Each oxygen molecule gains four electrons to form two oxide ions (O²⁻).
* These ions then combine to form zinc oxide (ZnO), a white solid.
The chemical equation for this reaction is:
2 Zn + O2 → 2 ZnO
Properties of Zinc Oxide:
Zinc oxide is a white, odorless powder that is widely used in various industries, including:
* Paints and coatings for its pigment and protective properties
* Cosmetics as a sunscreen and anti-inflammatory agent
* Rubber industry as a reinforcement and vulcanizing agent
* Medicine for its antibacterial and antifungal properties
Note:
The reaction between zinc and oxygen can occur at room temperature, but it is accelerated by heat. When zinc is heated in the presence of oxygen, it burns with a bright, white flame, producing zinc oxide as a white smoke.
