Oxygen is made of two oxygen atoms chemically bonded together to form a molecule, denoted as O₂.
Understanding the Composition of Oxygen
- Atomic Structure: Oxygen is a chemical element with an atomic number of 8, meaning it has eight protons in its nucleus. Source: scied.ucar.edu
- Molecular Structure: Unlike existing as a single atom, oxygen typically exists as a diatomic molecule (O₂). This means two oxygen atoms are strongly bound together by a covalent bond. Source: study.com
- Abundance in the Atmosphere: Oxygen makes up approximately 20.95% of Earth's atmosphere, primarily in this diatomic form (O₂). Source: britannica.com
Industrial and Practical Applications of Oxygen
Oxygen's diatomic nature is crucial to its many uses:
- Steel Production: A significant amount of oxygen is used in steel manufacturing.
- Plastics and Textiles: Oxygen plays a role in the production of these materials.
- Welding and Cutting: Oxygen is a key component in oxy-fuel welding and cutting processes.
- Rocket Propellant: Liquid oxygen is utilized as an oxidizer in rocket propulsion systems. Source: en.wikipedia.org
