Helium is a gas used to inflate lighter than air balloons.
Lighter than air balloons often use Helium as Hydrogen is too flammable for safe use.
An element used in some balloons is helium. It is a type of gas that is colorless and odorless. It is used in balloons because it is inert.
Balloons that float upwards in the air are filled with Helium. Hydrogen also works but it is extremely flammable and therefore dangerous so it is not used.
Baloons are filled with helium or hot air.

Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
Gases used are: air (and hot air), helium.
Silicon ... or more correctly silicon oxide.
The nonflamable element used in balloons is Helium, (He).

Helium is used for the ones that rise. Compressed air can be used or exhaled breath.
Gases used are: air (and hot air), helium.
Helium (Hydrogen could also be used but this is flamable). Not some balloons are also kept aloft using hot air.
