Oxygen

Health And Industrial Functions.

Oxygen

Oxygen is a colorless, odorless, and tasteless gas that makes up around 21% of the Earth’s atmosphere. Oxygen is a chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element that readily forms compounds with most other elements. Oxygen can exist in several different forms, including O2, O3 (ozone), and O4. O2, the most common form of oxygen, is a stable molecule consisting of two oxygen atoms bonded together.  Oxygen is Earth’s Most abundant element, and after hydrogen and helium.  Oxygen makes up almost half of the Earth’s crust in the form of oxides. All plants, animals, and fungus need oxygen for cellular respiration, which extracts energy by the reaction of oxygen with molecules derived from food and produces carbon dioxide as a waste product. 

In  tetrapods  breathing brings oxygen into the lungs where gas exchange takes place,
carbon dioxide diffuses out of the blood, and oxygen diffuses into the blood. The body’s circulatory system transports the oxygen to the cells, where cellular respiration takes place.

Many major classes of organic molecules in living organisms contain oxygen atoms, such as proteins, nucleic acids, carbohydrates, and fats, as do the major constituent inorganic compounds of animal shells, teeth, and bone. Most of the mass of living organisms is oxygen as a component of water, the major constituent of life forms. Oxygen is continuously replenished in Earth’s atmosphere by photosynthesis, which uses the energy of sunlight to produce oxygen from water and carbon dioxide. Oxygen is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms. Another form (allotrope) of oxygen, ozone strongly absorbs ultraviolet UVB radiation and the high-altitude ozone layer helps protect the biosphere from ultraviolet radiation. However, ozone present at the surface is a byproduct of smog and thus a pollutant.

Properties:

Here are some properties of oxygen: suffocating odor.

  • Physical State: At room temperature and atmospheric pressure, oxygen is a colorless,
    odorless, and tasteless gas.
  • Chemical Reactivity: Oxygen is highly reactive and readily reacts with many elements,
    including metals, nonmetals, and organic compounds. It is essential for combustion
    reactions and is often involved in oxidation reactions.
  • Solubility: Oxygen is moderately soluble in water, with a solubility of approximately 4.9
    milligrams per liter at 25°C (77°F).
  • Density: The density of oxygen gas is about 1.4 times that of air.
  • Isotopes: Oxygen has three stable isotopes, including oxygen-16, oxygen-17, and
    oxygen-18. Oxygen-16 is the most abundant, accounting for over 99% of natural oxygen.
  • Boiling and melting points: Oxygen has a boiling point of -183°C and a melting point of
    -218.4°C.
  • Oxidation State: Oxygen has an oxidation state of -2 in most of its compounds, although
    it can also exhibit other oxidation states in certain compounds.
  • Hazard: Oxygen gas is non-toxic, but it is highly reactive and can support combustion.
    High concentrations of oxygen can be hazardous and can cause fire or explosion if
    exposed to sparks or flames.

Uses

Oxygen has numerous applications in various industries, including:

  • Medical: Oxygen is used in hospitals and other medical settings to treat patients with
    respiratory problems. It is administered through an oxygen mask or nasal cannula to
    increase the amount of oxygen in the blood and alleviate breathing difficulties.

  • Welding and cutting: Oxygen is used in welding and cutting processes to provide the
    heat needed to melt metal. It is combined with fuel gas (such as acetylene) to produce a
    high-temperature flame that can cut through or weld metal.

  • Chemical production: Oxygen is used in the production of chemicals such as ethylene
    oxide, which is used in the manufacture of plastics, solvents, and detergents.

  • Steel production: Oxygen is used in the steelmaking process to increase the temperature
    of the furnace and accelerate the chemical reactions that convert iron ore into steel.
  • Aerospace: Oxygen is used in rockets and other spacecraft as a source of fuel and to
    provide breathable air for astronauts.
  • Water treatment: Oxygen is used in water treatment plants to help purify water by
    breaking down organic matter and other contaminants.
  • Scuba diving: Oxygen is used in scuba diving tanks to provide breathing air to divers at
    depth.
  • Ozone generation: Oxygen is used to generate ozone, which is used in water treatment
    and air purification systems to remove pollutants and disinfect water and air.

Although oxygen is essential for life, it can also be dangerous in certain circumstances. Oxygen is highly reactive and can easily ignite flammable materials, making it a fire hazard in certain industrial settings. In addition, high levels of oxygen in the air can be toxic, leading to symptoms such as nausea, dizziness, and respiratory failure.
