Why is helium used to fill balloons instead of oxygen or hydrogen?

Helium will not burn. Hydrogen burns in air to form H2O (water)
Thus in circumstances where a lite gas is required (e.g. in a balloon) it is safer to use Helium.

∙ 13y agoHelium is used to fill balloons instead of oxygen or hydrogen is because helium is lighter than air while oxygen and hydrogen are denser so they do not make the balloon float in the air because of gravity.

Is oxygen lighter than helium?
no. If it was, we would have oxygen balloons instead of helium balloons.
What chemicals do balloons contain?
helium or oxygen depending on what you put in them
This gas can be used to fill party balloons?
helium, hydrogen, nitrous oxide, oxygen
Explain why helium-filled Mylar-foil balloons can float freely for several weeks but latex balloons for less than 24-hours?
Helium is not only very light, it is also monatomic, it's particles are all made up of a single atom. Air molecules, oxygen, and nitrogen mainly are larger and hevier and diffuse through much more slowly.
Which of these is not a gas hydrogen gravity helium oxygen?
Hydrogen, helium and oxygen are gases. Gravity is a physical property of any substance.

Is balloons filled with hydrogen and oxygen?
If I am right in interpreting the question as "Are balloons normally filled with hydrogen and oxygen?", then the answer would be no. Although they can be, as both substances are gases, the majority of balloon are filled with air, a mixture of nitrogen, oxygen, carbon dioxide and other gases. If you mean the balloons that float, they are filled with helium
Is the oxygen sufficient for burning of hydrogen on the sun?
No. The hydrogen on the Sun does not burn; it fuses to make helium instead.
Can hydrogen and oxygen make helium?
Hydrogen an react with oxygen to form water and not helium
Why is helium used for balloons?
Because it's a lighter-than-air gas. Hydrogen could also be used, but hydrogen is extremely flammable, as the makers of the Hindenburg found out, whereas Helium does not react with oxygen and therefore will not burn.

How is the helium in the tank different from the helium in the balloon?
Helium balloons are usually mylar, a metal-coated plastic film while blow-up balloons are usually latex. Helium balloons are usually filled with helium of a decent purity, while blow-up balloons basically have the same gas mixture as the atmosphere around us. A little less oxygen and a little higher humidity if inflated by humans, exactly the same if inflated by a pump. Helium balloons will fly or float in the air, while blow-up balloons won't.

Hydrogen, helium and oxygen are gases. Gravity is a physical property of any substance.
The two elements most abundant in the universe are?
Hydrogen and helium are the two most abundant elements in the universe.
Which gas is most ideal helium oxygen hydrogen or xenon why?
helium
