yes. helium is lighter than earth or even air.
Helium is lighter than oxygen and can escape the ozone.
Helium is lighter than air
Hydrogen is lighter than Helium.
The composition of Earth's atmosphere is mostly nitrogen, carbon dioxide, and oxygen. All of these elements are denser than helium, and therefore it tends to rise.
because it's lighter
helium
No. Carbon dioxide is heavier than helium.
Helium is lighter than air and a balloon filled with helium may rise up.
Because helium is lighter than air. So helium balloon will rise up.
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
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.
