Rare gases, also known as noble gases or inert gases, are a group of chemical elements in group 18. Previously, these rare inert gases were called group 0 in the periodic table. Let Migco explore what inert gases are, what rare gases are, and the applications of various rare gases.
How many elements are in the noble gas group? This series of chemical elements includes helium, neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). In addition, ununquadium, an element in group 14, also exhibits characteristics similar to noble gases. Let’s explore the properties and applications of this group of rare gases.
Migco supplies various types of rare gases or inert gases in the periodic table with high purity. Rare gas selling price is competitive in the market, and we offer nationwide delivery.
What are rare gases and what are inert gases?
- Rare gases, also known as noble gases or inert gases, are chemical elements belonging to group 18 in the periodic table.
- The series of rare gas elements in the periodic table: helium, neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

- The ability of rare inert gases to undergo chemical reactions with other elements is very low. Therefore, rare gases become increasingly rare and depleted over time because they cannot be regenerated.
Characteristics of the rare gas group:
- As mentioned above, rare gas elements generally do not react, except under very special conditions.
- The inertness of rare gases in the atmosphere makes them suitable for applications where reactions are not allowed.
- The high inertness of the rare gas group can be explained by modern theories of atomic structure. The outermost shell of rare gas valence electrons is considered “full,” so they are less likely to participate in chemical reactions.
- The melting and boiling points of inert gases are close, with a difference of less than 10°C (18°F). This means that these gases only exist in liquid form within a small temperature range.
- Neon, Argon, Krypton, and Xenon are obtained from air. In air separation plants using liquefaction and fractional distillation methods.
- Helium is currently extracted from natural gas fields with high helium concentrations using cryogenic separation techniques.
- Radon is usually isolated from the radioactive decay of radium compounds.
Applications of rare gases, inert gases
These inert gases are widely used in everyday life activities and industrial production processes. Especially in lighting applications, such as incandescent lamps, helping to maintain the lifespan of the filament and create different beautiful colors…
Common applications of rare gases in practice include: arc lamps, use in airships, for MRI machines, luminous signs, refrigerants, and radiation therapy.
What are the uses of inert gases?
Each rare gas has specific applications. For detailed information on the applications of each rare gas, please refer to the individual gas below.
* Xenon:
- Low activity, emits multicolored light when used in non-discharge lamps
- Used as a general anesthetic
- Application of xenon rare gas in nuclear energy
- Xenon is an oxidizing agent in analytical chemistry
- Used in protein crystallography

* Neon
- Used in high-voltage indicator lamps, non-discharge lamps
- Lightning rods
- Used to create gas lasers
- Used in cooling or heat transfer technology in metallurgy
* Krypton
- Used to create krypton fluoride lasers
* Argon
- Used in non-discharge lamps, preventing the tungsten filament from oxidizing even when hot
* Helium
- Used in cooling technology, used for heat transfer in metallurgy…
- Used in breathing gas for deep-sea divers (heliox) to prevent the toxicity of oxygen, nitrogen, and carbon dioxide.
- Liquid helium is used to treat asthma and respiratory diseases.
- Helium gas allows airships and balloons to float in the air. Helium is also used in magic shows to change voice.

* Radon gas:
- Used in radiation therapy to control and destroy cancer cells…
The current situation of rare gases is that they are widely used, but they are gradually depleting because they cannot be regenerated, so the value of rare gases is also increasing.
Therefore, the demand for rare gases is increasing, and many units have chosen to sell low-quality and unreliable sources of rare gases. You need to choose a reputable and professional industrial gas supplier to purchase quality products that meet your usage requirements.
