The air you breathe out is denser.
EVERYTHING except hydrogen is denser than helium.
When you inhale hexaflouride gas you voice goes really low because hexaflouride gas is 6x denser than the air we breath... and i don't think you get a headache but when you breathe in helium, you get a headache. From a scale from1 to 10 of a headache from helium, it would possibly be a 5 which can hurt a lot. ^_^
Helium and neon are less dense than air; argon, krypton, xenon and radon are denser than air.
CO2 gas is more dense than the mixture of air we breathe. You can see this when dry ice sublimates.
Gases have no definite volume or shape. The air that you breathe, the helium in a balloon, and the neon inside the tube in a neon light are gases.
no its not
Because helium is less denser than air a helium balloon can rise; it is very simple !
Lots of things are denser than air. Mercury for example.
helium is less dense than the normal air we breathe, so when you breathe helium out and your vocal chords vibrate, it comes out in a higher pitch tone.
EVERYTHING except hydrogen is denser than helium.
The air we breathe contains 78% Nitrogen and 20% Oxygen. The remainder is Helium and other gases
from what i know about helium; it is lighter than air or the oxygen we breathe so it sits higher in your lungs. Therefore when you exhale it passes through your vocal cords faster which is why your voice is a higher pitch. If you breathe too much Helium in you will become light headed because you aren't getting the oxygen your cells need. An example of a different gas is xenon which is denser and heavier than air. Therefore when you breathe it in it sits at the bottom of your lungs and takes longer to pass through your vocal cords and makes your voice much deeper. It's pretty interesting however xenon is very expensive.

the air you breathe out is a mixture of oxygen, carbon dioxide sorry those are the only two that i definitely know i think there's a tiny bit of helium in there to
yes
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.
