Helium

Helium

 Helium (He) is a chemical element, the first of the periodic table’s noble gas group. The boiling point and melting point of helium are the lowest of all other substances, and its boiling point is -268.9°C. And it is the only element that cannot solidify by cooling at atmospheric pressure, regardless of temperature, only at 25 atm and a temperature of -272.2°C or below will it become solid. It is a colorless, tasteless, odorless, and inert monatomic gas. Helium is very light; it is the second lightest gas in the periodic table. As a result, Earth’s gravity is not strong enough to hold it in its atmosphere. Therefore, when helium gas is released, it will rise up and eventually escape into space.

Some Applications of Helium:
    • Magnetic Resonance Imaging (MRI) Cooling
    • Lifting
    • Cryogenic Applications
    • Semiconductor Processing
    • Research and Analytical Applications
    • Aerospace Pressurizing and Purging
    • Leak Detection
    • Welding Applications
    • Breathing mixtures
Helium is produced by:

There is currently no way to produce helium on an industrial scale on Earth, it is mainly extracted. All commercial helium is recovered from underground deposits, which is a result of the natural decay of radioactive material within the Earth. However, this process is slow and does not produce helium on an industrial scale. Helium usually makes up a tiny portion of the natural gas deposit but can make up as much as 10% of natural gas in some fields.
