It is a matter of mass, weight, and density. A balloon filled with normal air will not rise. Air will rise in water, because it is less dense (bubbles). Helium on the other hand is lighter than air, so it too will rise when 'submerged' in it. The actual process is that the heavier air surrounding a helium-filled balloon will "displace it" and force it upward.
Hydrogen is also less dense than air, but it is flammable. Helium is not flammable, has no smell or taste, and is not poisonous. So because it is the second lightest element, and the second most plentiful in the world (found in natural gas), it's a natural fit.

However, consider that while it may seem fun to have balloons that go up on a string, if they escape, then eventually they pop and it is likely that the burst rubber will fall into the sea. In the sea they are mistaken for food by turtles and escaped balloons cause much harm.
Also being unreactive as an element and very light, most of the helium on earth has gone to the top of the atmosphere and escaped into space. The only helium we have is found as a byproduct of radioactive decay within the Earth. The element has very important uses in industry and science and wasting it on balloons is not a sensible thing to do. There is only a finite amount of helium available to us at any given time.
Helium is a colorless gas that is commonly used to fill balloons to make them float. It is lighter than air and non-flammable, making it safe for use in balloons.
They Do Not use Hydrogen gas to fill up balloons. People use Helium gas to fill up balloons (ordinary party balloons, and big working balloons such as the one used by Goodyear). Helium is Not Flammable. Hydrogen is Flammable and has as tendency to burst into Flame, similar to the German Blimp/Dirigible Hindenburg. Since the US Navy lost Two Helium Blimps in Bad weather; The Akron and the Shenandoah (with a great loss of lives), the US Navy almost never uses Blimps anymore.
Yes, helium is used widely in various applications such as party balloons, airships, as a coolant in nuclear reactors and MRI machines, and in cryogenics for preserving biological samples. However, there is a concern over helium scarcity as it is a non-renewable resource.
Yes it is a gas. It is used commonly to fill balloons.Yes
Helium is commonly used in balloons to make them float and in airships for lift. It is also used in cryogenics, as a coolant in nuclear reactors, and in MRI machines for cooling the superconducting magnets.
Helium is typically used to fill airships and balloons due to its low density, which allows them to float in the air.
If you want the balloons to float, you would probably use helium.
Helium at room temperature is commonly used to inflate balloons due to its low density, making balloons float.
Helium gas is commonly used to fill party balloons because it is lighter than air, making the balloons float.
Helium is commonly used to fill balloons. It is non-flammable and lighter than air, allowing balloons to float.
No, helium balloons are not radioactive. Helium is a non-toxic, inert gas often used to fill balloons because it is lightweight and does not react with other chemicals. It is safe for decorations and festivities.
Helium is a colorless, odorless, and tasteless inert gas that is used in various applications such as in balloons for parties and in cryogenics for cooling superconducting magnets.
Helium gas is most commonly used to fill balloons to make them float. Helium is lighter than air, which causes the balloon to rise and float.

Because helium is lighter
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
One example of a gas would be helium. Helium is used to fill up balloons and make them float.
