Helium is one single type of gas. It is made of two Electrons, two Neutrons and two Protons. 2 is the most powerfully "Magic Number" which has nothing to do with magic and wizards but with Atom-Stability. Helium wouldn't burn even if you put it into the Core of the Sun(The place where it comes from, as the "Smoke" from the Thermonuclear Fusion which warms you when you stand outside in summer)
Air is a Mixture of Nitrogen(Colorless, ignites at 6000°C, like inside a lightning-bolt) , Oxygen(Also colorless, although a slight shade of blue, which you only notice when you look through a MASSIVE Amount of it, like when it is liquefied or when you look at the Sky, Which is used to BURN things, such as the sugar and fat which powers your body) and CO2(Which is, together with Water the product of Powering your Body/Car/Cat, ect.) then there is a multitude of other gases mixed into it, like Sulfuric oxide or... HELIUM!
Oh, and another thing: Nitrogen has 7Neutrons, electrons and protones, Oxygen 8! So Air is nearly four times as heavy as Helium meaning if you put it a lot of Helium into something which is not too heavy this thing will fly. It also means you will have a lighter Voice if you breathe it in, but remember that it does not contain Oxygen, so if you don't let it out of your lungs again(like when you do a headstand and it cannot fly up and out of you) you will suffocate.

Will a helium balloon float in below freezing weather?
Yes, its to do with the gas density difference of air and helium, rather than the density of gas due to temperature.
Which has the least density between ammonia air oxygen helium and chloride?
balloon
Is Density of helium balloon is greater or less than air?
The density of helium is less than that of air. Due to this reason, balloons filled with helium will float in air.
Why does a helium ballooon float in air?
Helium has a lower density than air.
How dense is helium compared with air?
Which is more dense: water or helium? - Water is more dense, because water does not float like helium does. It is below air. That's why we have oceans and lakes and rivers.
Will a helium balloon float in below freezing weather?
Yes, its to do with the gas density difference of air and helium, rather than the density of gas due to temperature.
What is difference between density in air and density in vacuum?
subtract 0.0011 from the density in vac to get density in air.
What difference between density in air and density in vacuum?
subtract 0.0011 from the density in vac to get density in air.
Which has the least density between ammonia air oxygen helium and chloride?
balloon
Is Density of helium balloon is greater or less than air?
The density of helium is less than that of air. Due to this reason, balloons filled with helium will float in air.
Why does a helium ballooon float in air?
Helium has a lower density than air.
What is the difference in density between warm and cold air?
The density between cold and warm air is, cold air is heavier than warm air.
What makes helium great to use in balloons and blimps?
Helium's density is less than the density of air, so it floats in air.
What is the difference between helium and iron?
Helium is a gas that is lighter than air. Iron is a solid metal and is heavy.
Does helium have more density than air?
Yes, all substances have density. Helium has a density of 0.1664 g/liter at 20°C and one atmosphere of pressure.
What has more density air or helium?
The density of helium is less than the density of air. You can infer this without doing any calculations by thinking about the classic example of inhaling the helium from a balloon and talking. Your voice gets squeeky high because helium is less dense than air - that is, your sound waves propagate faster through helium than through air, therefore helium is less dense.
Is a canster of air lighter than a canster of helium?
No, helium has the second lowest density out of all the elements and with Hydrogen having the smallest density but it not being in the air it means the canister of air is heavier.
