Helium-filled objects "float" in most substances that aren't primarily hydrogen or helium because of it's less dense. Helium has a weight of 0.1785 grams per liter. Nitrogen, on the other hand, which makes up 80% of the air we breathe, weighs 1.2506 grams per liter. Things that are lighter over the same surface area are more buoyant.
However, helium isn't the lightest element. Hydrogen, weighing a mere 0.08988 grams per liter, is. The reason hydrogen isn't used as commonly as helium to fill things is because of the high flammability of hydrogen, with a small spark causing a hypothetical hydrogen balloon to explode.

What chemical makes things float?
Often the element helium (atomic symbol: He) often makes objects float, most commonly balloons.
Does helium float or sink?
Helium is light and it will float / rise.
Can helium make you float?
no
Does helium float or sink in air at room temperature?
Helium is lighter than air. So it will float in air.
Why does a helium balloon float up when it is released?
Because helium is lighter than air. So helium balloon will rise up.
What makes balloons float when they are full of air but not float when they are deflated?
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
What does helium have in it that makes it float?
Helium is lighter than air. Hence balloons or blimps filled with helium will float.
What makes a party balloon float?
Helium!
What makes a helium balloon float?
helium is a light mass of weight in which will float unlike a hevy object that will fall to the ground
Why do baloons float in air?
Balloons are full of a gas called 'helium', which is lighter than air. The helium is trapped inside the balloon, that's what makes it float.
What chemical makes things float?
Often the element helium (atomic symbol: He) often makes objects float, most commonly balloons.
What is helium and What is its use for?
its the 2nd element on the periodic table and it makes things lighter, such as helium balloons, which float as helium is lighter than air
Does helium float or sink?
Helium is light and it will float / rise.
Why does a helium balloom float in air?
Helium is lighter than air. so balloons filled with helium will float in air
Does a human body float in helium gas?
No, human body doesn't float on helium as it is light.
Does a helium balloon float with anything inside?
Helium
Will warming helium balloons make them float?
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
