What are 5 facts about helium?

Ten Facts about Helium

Helium is the second most abundant element in the universe, and the second lightest element.
It is estimated that our sun produces 700 million tons of helium per second.
Helium has the lowest boiling point of all elements—4.2 degrees Kelvin (that -268.8 Celsius)—just 4 degrees above absolute zero.

Where is helium in the periodic table?

Group 18
Helium and neon, the two lightest noble gases, have been traditionally positioned by IUPAC in the Group 18 of the Periodic Table of Elements, together with argon, and other unreactive or moderately reactive gaseous elements (krypton, xenon, radon), and oganesson.

What is helium period?

Helium is the second element on the periodic table. It is located in period 1 and group 18 or 8A on the righthand side of the table. This group contains the noble gases, which are the most chemically inert elements on the periodic table.

What are 3 uses helium?

Helium is used for medicine, scientific research, arc welding, refrigeration, gas for aircraft, coolant for nuclear reactors, cryogenic research and detecting gas leaks. It is used for its cooling properties because of its boiling point being close to absolute zero.

What is helium most used for?

Because it is very unreactive, helium is used to provide an inert protective atmosphere for making fibre optics and semiconductors, and for arc welding. Helium is also used to detect leaks, such as in car air-conditioning systems, and because it diffuses quickly it is used to inflate car airbags after impact.

Who uses the most helium?

The biggest consumer of helium is NASA, using annually almost 75 million cubic feet, followed by the USA Department of Defense, which uses a significant quantity to cool liquid hydrogen and oxygen for rocket fuel.

Is there a substitute for helium?

Argon can be used instead of Helium and is preferred for certain types of metal. Helium is used for lots of lighter than air applications and Hydrogen is a suitable replacement for many where the flammable nature of Hydrogen is not an issue.
