The name is
derived from the Greek, ‘helios' meaning sun
, as it was in the sun's corona that helium was first detected.
Who discovered helium?
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.
Who named helium?

What does helium stand for?
EXPLORE. Helium is a chemical element. Its official symbol is
He
, and its atomic number is 2, which means it has two protons in its nucleus. Helium was named after Helios – the Greek Titan of the Sun – because it was first observed when analysing sunlight during a solar eclipse in 1868.
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.
Can we make 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.
Can we survive without helium?
Helium is the only element on the planet that
is a completely nonrenewable resource
. On Earth, helium is generated deep underground through the natural radioactive decay of elements such as uranium and thorium.
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 |

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.
What are the weaknesses of helium?
Although helium normally has a valence of zero, it has
a weak tendency to combine with certain other elements
. Uses: Helium is widely used in cryogenic research because its boiling point is near absolute zero.
Where do you get helium?
Nearly all of our helium is extracted from
natural gas
, a byproduct of radioactive decay of uranium and thorium. Much of the extraction in the United States and the world comes from underground gas fields between Amarillo, Texas, and Hugoton, Kansas, where a very high concentration, up to 2%, can be found.
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.
Where is helium found naturally?
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
.
How many shells are in helium?
Helium only has
one atomic shell
, which fills up when it has two electrons.
