Helium is important because it is used to raise balloons of the ground to often defy gravity
answ2. This gas has the low temperature record - it does not freeze - and is used extensively as a coolant in MRI machines, and Cryogenics in general.
answ 3 - Helium is used in fuel rods of CANDU reactors to fill the gap between uranium dioxide and zircaloy 4
- Gas for leak detection
- Welding in inert atmosphere
- Inert atmosphere for the preparation of special alloys, metals, semiconductors etc.
The chemical symbol for helium is "He."
The symbol of Helium is He. Helium's atomic number is 2.
AnswerThere are two variants of helium -- helium 3 and helium 4. Helium 4 is not magnetic but helium 3 is. Its magnetism is, however, of different nature than e.g. that of iron. The magnetism of helium 3 is used for medical lung imaging.
Helium is a nonmetal. Think about the helium balloon!
Helium can change the tone of a humans voice in an helium-rich atmosphere.
The important property is the inertness of helium.
becouse it is important
helium is used in gas ballons .it is the lighter gas
Helium is not important for living beings.
Helium is an inert gas.
Helium is the second lightest element. Helium has the lowest boiling point among all the elements. It is chemically inert.
Helium is the second lightest element and the second most abundant element in the observable universe.
helium is used in airoplanes tyres..balloons...sun shine...sea driver mix it with oxygen..etc
No. You can live without aluminum or helium, but you cannot live without iodine.
Helium is a lighter-than-air gas, so it's handy for filling balloons with. Probably more "important" than that though is the fact that helium is not very reactive (it is chemically inert), and in particular it is not flammable, unlike hydrogen.
