Helium is used for inflating balloons and dirigible airships.
No one chemical property is known for Helium.
One atom is too small to see. A helium atom is the smallest type of atom.
HELIUM
They form a mixture of argon and helium. Both argon and helium are noble gasses, meaning that the do not usually react and certainly will not react with one another.
Sulfur dioxide diffuses at one-quarter the rate of helium
it can be used to fill helium balloons
helium balloons
You can use air but it won't float so I would recommend helium. If you suck in helium, it will make your voice sound weird.... Try it!!
helium is used for excitation of neon atoms in helium neon laser..
Helium has one kind of atom: helium.
Helium has only one type of gas (which is helium itself)
Inhale
The balloon with helium.
ONE, Helium is an element, not a molecule.
The symbol of the element helium is He(one of the noble gases).
Liquid helium is used to cool the superconducting electromagnets.
the use for balloons mostly
