What are some natural resources of particles in the atmosphere?
oxygen,helium,carbon dioxide,nitrogen
Why does helium float?
Helium molecules are lighter than most air molecules in the atmosphere (mostly nitrogen and oxygen) therefore they are prone to rise while heavier molecules move downward.
Which is lighter oxygen helium or nitrogen?
Helium
What is helium nitrogen?
Helium and nitrogen are two gasses that occur in the earth's atmosphere. Nitrogen is the most common gas in the atmosphere, at 78%. Helium is much less common at only 0.0005%.
Where are the particles of helium farthest apart in a tank or in a balloon?
The particles of helium are farthest apart in a balloon.

oxygen,helium,carbon dioxide,nitrogen

What molecules make up nitrogen?
nitrogen is an atom, it isn't made up of atoms, though all elements are made up of hydrogen and helium
Why is there nitrogen in helium?
Um... because the helium was insufficiently purified? There is no nitrogen in pure helium.
What is the chemical formulas for helium and nitrogen?
Helium is He Nitrogen is N2
Is nitrogen and helium a hot gas?
yes helium and nitrogen are hot gases
Which is lighter oxygen helium or nitrogen?
Helium
3 elements which exist as 2 atom molecules?
Oxygen, Nitrogen, and Sulfur. (Though in the latter case, S2 is not the most common allotrope of Sulfur, the allotrope DOES exist.)
What has a higher velocity helium or oxygen?
At the same temperature and prssure in a gas the helium atoms will on average move faster than the O2 molecules.
What makes the balloon rises?
Helium gas in the balloon causes it to rise as it is much less dense than the surrounding air which has heavier molecules such as Oxygen, Nitrogen, Carbon Dioxide, etc.
What is helium nitrogen?
Helium and nitrogen are two gasses that occur in the earth's atmosphere. Nitrogen is the most common gas in the atmosphere, at 78%. Helium is much less common at only 0.0005%.
