Negative oxygen ion is a kind of physical substance with negative charge, which is common in nature, especially in the air. The physical properties of negative oxygen ions are very important because they not only help to improve air quality, but also have a positive impact on human health.

Formation reason

There are many reasons for the formation of negative oxygen ions.

In nature, negative oxygen ions can be produced by natural phenomena such as photolysis of water, lightning activity, ocean waves, and waterfall splashing. When sunlight hits water molecules, they break down into oxygen and hydrogen, releasing negative ions. Lightning activity generates a strong electric field in the atmosphere, ionizing the gas molecules in the air and producing negative ions. Negative ions are also released in bubbles created by crashing waves in seawater, and a waterfall splash can produce large amounts of negative ions.

In artificial devices, negative oxygen ions can be generated by air purifiers, negative oxygen ion machines and other devices. Air purifiers use filters and ionization technology to filter out pollutants in the air and ionize oxygen molecules through a high-pressure electric field to produce a large number of negative ions. Negative oxygen ion machines (especially those that simulate the Renard effect) separate negative oxygen ions by pressurizing air and impacting pure water to create friction.

constituent

The negative oxygen ion is mainly composed of oxygen atoms and its chemical formula is O2-. Oxygen atom is a non-metallic element, which exists widely in nature and is one of the indispensable elements in all living substances. Oxygen has an atomic number of 8 and an atomic radius of 66 pm. In the negative oxygen ion, the oxygen atom gains an electron, has a negative charge, and becomes the O2- ion. Since the oxygen atom is highly electronegative, the O2- ion is also highly electronegative and easily combines with other positively charged ions or molecules.

In addition to oxygen atoms, negative ions may also contain other elements, such as negative hydrogen ions (H-), negative nitrogen ions (N-), and so on. These ions also occur frequently in nature, and they can be produced by various chemical reactions, such as electrolysis of water, electrolysis of ammonia water, and so on.

Charge characteristic

The negative oxygen ion has a negative charge, and its charge characteristics are similar to other negative ions. In nature, the charge characteristic of negative ions is very common, and they can be produced by various chemical reactions. The charge characteristics of negative ions make them highly hydrophilic and can adsorb water molecules and water vapor in the air, thereby improving air humidity. In addition, negative ions can also adsorb particles such as dust, bacteria and viruses in the air, thereby purifying the air.

In the indoor environment, due to the existence of various electronic devices, a large number of positive ions will be produced in the air, such as TV sets, computers and other equipment will release positive ions. These positive ions are harmful to human health, such as causing headaches, fatigue and other symptoms. Negative ions can neutralize these positive ions, so that the charge balance in the air is adjusted, thereby improving air quality.

Finally, as a kind of physical substance, it is also very important for us to understand its formation, composition and charge characteristics, and it is also of great significance for us to further understand the mechanism of action and application value of negative oxygen ions.
