What is the Helium? – Definition, Uses, and More

Definition of Helium

Helium, the lightest of the noble gases, remains detected, and Helium is the only element in the periodic table that an astronomer discovered.

We can find it on the upper right side of the periodic table with atomic number 2. It comes first amongst the family of noble gases.

It held one atomic orbital and the name Lockyer and Frankland. Its name derives from the Greek word “Helios,” meaning Sun. Scientists knew there is an enormous amount of it in the Sun before it discovers.

Also, it falls under inert gas since its outermost electron orbital is full of two electrons. It can also found in lasers, compressed air tanks, and coolants in nuclear reactors.

And it holds the lowest boiling and melting points amongst all the other elements. The Nuclear fusion of hydrogen in stars makes the significant amount of Helium.

Isotopes

Its two known stable isotopes – He and He. The abundance of helium-3 and helium-4 agrees to 0.0002% and 99.9998%, respectively. This difference in quantities can observe in the Earth’s atmosphere, where the ratio of He atoms to He atoms is approximately 1000000:1.

What are the Uses of Helium?

The main uses of the Helium energies in altitudes it research and meteorological balloons.

And its use as the inert protective gas in autogenous welding.

Also, it’s the only cooler capable of declining temperatures lower than 15K (-434ºF).

And it is also used in the production of germanium crystals and silicon crystals.

Since it can diffuse through solids much faster than air, Also is used industrially for pipeline leak detection.

And element also uses in gas chromatography as a carrier gas.

Also, owing to its low melting point, liquid Helium

It has numerous applications in cryogenics, magnetic resonance imaging (MRI), and superconducting magnets.
