It is usually found in natural gas wells. (Most of the Helium found on Earth is the result of radioactive decay (Alpha particles).
August 18 and October 20, 1868: Discovery of Helium. Photos by Wikipedia Commons. 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. Helium is the smallest and the lightest noble gas and one of the most unreactive elements, so it was commonly considered that helium compounds cannot exist at all, or at least under normal conditions. Helium's first ionization energy of 24.57 eV is the highest of any element. Helium has a complete shell of electrons, and in this form the atom does not …Helium tanks are a common tool used in many industries, from welding to party decorations. But when they’re empty, disposing of them can be tricky. It’s important to find a local facility that can safely and responsibly dispose of your heli...laser. Laser - Invention, Light Amplification, Coherent Beam: The laser is an outgrowth of a suggestion made by Albert Einstein in 1916 that under the proper circumstances atoms could release excess energy as light—either spontaneously or when stimulated by light. German physicist Rudolf Walther Ladenburg first observed stimulated emission in ...
Lockyer called the new element helium, after the Greek word for sun. Both Janssen’s and Lockyer’s papers describing their observations landed at the French Academy of Sciences on the same day, and both men received credit for the discovery of the “new” element.

Jun 28, 2016 · Huge helium discovery 'a life-saving find'. A new approach to gas exploration has discovered a huge helium gas field, which could address the increasingly critical shortage of this vital yet rare element. Helium doesn’t just make your voice squeaky – it is critical to many things we take for granted, including MRI scanners in medicine ... Aug 17, 2018 · Helium is also the first superfluid ever discovered. When cooled below 2.17 Kelvin, its viscosity – a parameter for measuring the thickness of a liquid – becomes zero. This gives helium freaky, superfluid properties, such as being able to sustain a vortex forever and to creep up the surface of a bowl and drip down its side. Andrea Sella, Professor of Inorganic Chemistry at University College London, celebrates the art and science of the chemical elements.
