Product Description

Product Description

Helium gas is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, and non-toxic gas. Helium is the second lightest and second most abundant element in the universe, after hydrogen. Here are some key points about helium gas:

1. Chemical Symbol: He
2. Atomic Number: 2
3. Atomic Weight: 4.0026 g/mol
4. Physical Properties: Helium is a noble gas and exists as a monatomic gas at standard conditions. It has a low boiling point (-268.93°C or -452.07°F) and a low melting point (-272.20°C or -457.96°F). Helium gas is lighter than air and has a density about one-seventh that of air.
5. Abundance and Occurrence: Helium is the second most abundant element in the universe, primarily formed through nuclear fusion in stars. However, it is relatively rare on Earth. It is obtained as a byproduct during the extraction of natural gas, where it is found in small quantities in underground gas deposits.
6. Applications: Helium has several important applications. It is commonly used as a coolant in various scientific and industrial applications, such as cooling superconducting magnets in MRI machines, particle accelerators, and nuclear reactors. Helium is also used in cryogenic research, as a carrier gas in gas chromatography, and in certain types of welding. Additionally, helium is widely used in filling balloons, airships, and blimps due to its low density.
7. Liquid Helium: When cooled to extremely low temperatures, helium undergoes a phase transition and becomes a liquid. Liquid helium is used in cryogenics for achieving temperatures close to absolute zero (-273.15°C or -459.67°F). It is used to cool superconducting materials and conduct experiments at extremely low temperatures.
8. Safety Considerations: Helium gas is generally considered to be non-toxic and does not pose significant health hazards. However, it can displace oxygen in confined spaces, leading to asphyxiation. Proper ventilation and safety precautions should be followed when working with helium in enclosed areas.
9. Helium Shortage: Helium is a finite resource on Earth, and there have been concerns about its availability and supply in recent years. The extraction and storage of helium are important considerations to ensure its sustainable use in various applications.
10. Historical Significance: Helium was first discovered in 1868 by French astronomer Pierre Janssen, who observed a yellow spectral line in the sun during a solar eclipse. Its name "helios" comes from the Greek word for the sun, reflecting its discovery in the sun's spectrum.
