Product Description

Helium gas is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, and tasteless gas that belongs to the noble gas group in the periodic table. 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 very light gas, being the second lightest element after hydrogen. It is less dense than air and has a density of about 0.1785 grams per liter at standard conditions. Helium has a boiling point of -268.93 degrees Celsius (-452.07 degrees Fahrenheit) and a melting point of -272.2 degrees Celsius (-457.96 degrees Fahrenheit).
  5. Abundance and Occurrence: Helium is the second most abundant element in the universe, but it is relatively rare on Earth. It is produced through the decay of radioactive elements, such as uranium and thorium, and accumulates in natural gas deposits. Helium is often extracted from natural gas wells.
  6. Applications: Helium gas has various practical applications. It is commonly used as a coolant in cryogenics and superconductivity research, where its extremely low boiling point is beneficial. Helium is also widely used in scientific research, such as in gas chromatography and as a carrier gas in analytical instruments. Additionally, helium is used in industries like welding, leak detection, and as a lifting gas for balloons and airships.
  7. Liquid Helium: Helium can exist in a liquid state at extremely low temperatures. Liquid helium has unique properties, including superfluidity and superconductivity, which make it valuable for research in low-temperature physics and the production of superconducting magnets.
  8. MRI Scanners: Helium is essential for cooling and maintaining the superconducting magnets used in magnetic resonance imaging (MRI) scanners. The low temperatures achieved by liquid helium enable the magnets to function efficiently.
  9. Safety Considerations: Helium gas is generally considered to be non-toxic and does not pose significant health hazards. However, it is an asphyxiant and can displace oxygen in poorly ventilated areas, leading to suffocation. Proper ventilation and handling precautions are necessary when working with large quantities of helium gas.
  10. Conservation: Helium is a non-renewable resource, and its availability is limited. Due to its importance in critical applications, helium conservation and responsible usage are encouraged to ensure its availability for future generations.
