helium is a gas. air is a bunch of different gasses.
Pure helium is made of elemental helium only and is a gas at STP. It will not have air.
helium is the lightest air
air is more dense than helium
Balloons are filled with gas (such as helium), or a mixture of gasses (such as air) or hot gasses (such as hot air).Helium.
No, hot air balloons, as the name suggests, contain hot air, not helium.

Helium is a gas that is less dense than air. This is why a balloon filled with helium rises when released.
helium gas is warmer than air.
Those balloons are filled with helium gas. Helium is lighter than air. Helium is a noble gas.
No, helium and hot air are not the same gas. Helium is a noble gas that is lighter than air, while hot air is a mixture of gases heated to a higher temperature than the surrounding air. Helium is commonly used to fill balloons because it is non-flammable and provides buoyancy.
Helium does not exist in atmosphere as it is a very light gas.
