Helium is an element that is less dense than the air around it. This is because it is sooner on the Periodic Table (BY FAR) than all the other elements such as Nitrogen which is 70% of the air. As you should know, the elements have a weight and volume. Density is weight divided by volume, so elements sooner on the periodic would be less dense being lighter. So, the helium in the balloon and the weight of the balloon are together less than the air around it all, so it floats. Incidentally, balloons filled with air can indeed float, as many ballooning hobbyists know. Air expands as it is heated, and as a result it is less dense than the surrounding air. Balloons filled with hot air will float.
A balloon floats with helium and not air because helium is less dense than the air, which is mostly nitrogen and oxygen. A less dense substance will float on a more dense substance, whether we're talking about a solid and a liquid, two or more liquids, or gases.
Helium is lighter than air so it lifts up when released.
Helium is lighter than air, hence balloons filled with helium will rise up in air.
An object will float if it has less density than the medium in which it is supposed to float or sink. In this case, the baloon + helium weighs less than the same volume of air.
Because helium is lighter than air.
The helium weighs less than air- so when the balloon is filled, it displaces the heavier air, and floats. Just as a bit of wood weighs less than water, and floats on water. In a vacuum, a helium filled balloon would not float (but it may pop)
I'm not sure I understand the question but here goes: Helium is lighter [less dense] than air, so a helium filled balloon rises because it floats up on the more dense air.
A helium balloon floats because helium gas is lighter than air. By filling a balloon with helium, the balloon also becomes lighter than air. The helium balloon floats for the same reason that objects float on water: objects less dense than water are pushed up by buoyant forces equal to the weight of water displaced by that object. What happens in water also happens in air, and the helium balloon is pushed upwards by a force equal to the weight of air it displaces.
Helium is lighter than air and a balloon filled with helium may rise up.
No. Helium is lighter than air
Helium is less dense than air, which is why the helium-filled balloon floats when you let it go.
Helium is lighter than air. hence helium balloon will float in air.
Helium is less dense than air
A Helium filled baloon floats in air because Helium is lighter than air. Making it rise to the top of it.

A balloon filled with helium floats and a balloon filled with regular air falls to the ground because helium has less density than air so the air causes the balloon to sink because there are more molecules in it. The helium has less molecules in it so the balloon rises.

Its filled with gas because certain gases(Helium, Hydrogen) are lighter than air so they float. That's why the balloon floats.

because helium is a source of of air but not exactly air because it has the compounds to push against air to fly up unlike ex. if i filled a balloon with air and one with helium the one with air can floats but goes back down but the on helium floats off because its atoms in the balloon are jumping around and it has sub atomic cells
Helium is lighter than air and a balloon filled with helium may rise up.
