History. Helium was discovered in the gaseous atmosphere surrounding the Sun by the French astronomer Pierre Janssen , who detected a bright yellow line in the spectrum of the solar chromosphere during an eclipse in 1868; this line was initially assumed to represent the element sodium.

How did helium get discovered?
Discovery and Naming:
The first evidence of helium was obtained on August 18th, 1868 by French astronomer Jules Janssen. While in Guntur, India, Janssen observed a solar eclipse through a prism , whereupon he noticed a bright yellow spectral line (at 587.49 nanometers) emanating from the chromosphere of the Sun.
When did helium get discovered?
August 18 and October 20, 1868 : Discovery of Helium. Pierre Janssen (top) and Joseph Norman Lockyer (bottom), discovers of helium. Despite being the second most abundant element in the observable universe, helium is relatively rare on Earth, the product of the radioactive decay of elements like uranium.
Where is helium found?
Where on earth is helium found? Wherever large deposits of uranium are located, Helium will also be found. Most of the world’s Helium comes as a byproduct of decaying uranium and fossil fuels. Today, the world’s Helium supply relies on reserves in the United States, the Middle East, Russia and North Africa .
Can we create helium?
Helium is all over the universe—it’s the second-most abundant element. But on Earth, it’s much less common. It can’t be artificially produced and must be extracted from natural gas wells . ... Over time, helium forms from the decaying uranium and is trapped beneath Earth’s surface, but it takes its sweet time.
How much helium is left in the world?
In 2014, the US Department of Interior estimated that there are 1,169 billion cubic feet of helium reserves left on Earth. That’s enough for about 117 more years. Helium isn’t infinite, of course, and it remains worth conserving.
Why is there a helium shortage 2020?
As demand for party balloons —which account for 10% or more of total helium use, according to market consultant Phil Kornbluth—disappeared in March, and as industrial demand slowed in concert with shelter-in-place orders, the global helium supply crunch of the past two years abruptly ended.
What are five uses for helium?
- Heliox mixtures in respiratory treatments for asthma, bronchitis and other lung deficiencies. ...
- MRI magnets. ...
- High speed Internet and Cable TV. ...
- Mobile phone, computer and tablet chips. ...
- Computer hard drives. ...
- Cleaning rocket fuel tanks. ...
- Microscopes. ...
- Airbags.
Are we running out of helium?
Although it is rare on Earth, you likely have encountered it in helium-filled balloons. ... Once the gas leaks into the atmosphere, it is light enough to escape the Earth’s gravitational field so it bleeds off into space, never to return. We may run out of helium within 25–30 years because it’s being consumed so freely .
What is the price of helium?

How many shells are in helium?
Helium only has one atomic shell , which fills up when it has two electrons.
How did Jules Janssen discovered helium?
Discovery of helium
In 1868 Janssen discovered how to observe solar prominences without an eclipse . While observing the solar eclipse of 18 August 1868, at Guntur, Madras State (now in Andhra Pradesh), British India, he noticed bright lines in the spectrum of the chromosphere, showing that the chromosphere is gaseous.
What happens if we run out of helium?
If our supply ran out, it could spell the end of MRI testing, LCD screens and birthday-party balloons . Or it could make all of those things much more expensive. Although argon — another inert gas — can be substituted for helium for welding purposes, no other element can do what helium can do in supercold applications.
What is the color for helium?
| Helium | Pronunciation /ˈhiːliəm/ (HEE-lee-əm) | Appearance colorless gas, exhibiting a gray, cloudy glow (or reddish-orange if an especially high voltage is used) when placed in an electric field | Standard atomic weight A r , std (He) 4.002602(2) | Helium in the periodic table |

How can I buy helium?
You can buy HNT on FTX Exchange and Binance.US . Helium is a decentralized internet service built to power the Internet of Things (IoT). While Bitcoin miners verify transactions are legit, Helium miners run hot spots that emit a low-frequency signal across a large radius.
