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.
What else can I help you with?
Why do you have to hang onto your helium balloon?
Helium is lighter than air, so it makes the balloon float. If you let go of the balloon, it will float up into the atmosphere because of the difference in density between the helium inside the balloon and the air outside.
Why does a helium ballooon float in air?
Helium has a lower density than air.
Which has the least density between ammonia air oxygen helium and chloride?
Helium has the least density among the substances listed. It is a very light gas and is less dense than air, oxygen, ammonia, and chloride.
Is Density of helium balloon is greater or less than air?
The density of a helium balloon is less than that of the surrounding air. This is why helium balloons float in the air. Helium is lighter than the nitrogen and oxygen that make up the majority of Earth's atmosphere, so it provides buoyancy for the balloon.
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.
What is the difference between having helium in a balloon and having air in a balloon?
Helium is lighter than air, so a balloon filled with helium will float. In contrast, air-filled balloons will sink because the density of air is greater than that of helium. Additionally, helium balloons will deflate faster than air-filled balloons due to its smaller molecular size.
Why do you have to hang onto your helium balloon?
Helium is lighter than air, so it makes the balloon float. If you let go of the balloon, it will float up into the atmosphere because of the difference in density between the helium inside the balloon and the air outside.
What do you blow up a balloon to make it fly?
Helium gas is typically used to fill balloons to make them float or fly. Helium is lighter than air, so it causes the balloon to rise due to the difference in density between the helium gas inside the balloon and the surrounding air.
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.
Why does a helium ballooon float in air?
Helium has a lower density than 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 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.
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.
Which has the least density between ammonia air oxygen helium and chloride?
Helium has the least density among the substances listed. It is a very light gas and is less dense than air, oxygen, ammonia, and chloride.

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.
How much mass can a balloon filled with 200 m3 helium lift when the density of helium is 17 and the density of air is 1800?
Ftotal= B - Fg = 0 (B = Buoyant Force; Fg = Weight of mass) B = Fg (pf - po) * Vo * g = m * g (p = rho, density of fluid, air, and of object, balloon multiplied by volume of balloon, g cancels out.) (1800-17) * 200 = m m = 356600 units (units depends on what density value you were given. Typically they are in kg/m3, but these densities are very high for kg/m3.)
