How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
Why does the helium balloon rise while the ordinary air failed?
Helium is a very light compound. Air consists out of 21 % oxygen gas, 78% nitrogen gas and 1% other gases (such as argon and other noble gases) in general. As we know, wood floats on water because it is lighter per volume. For helium, the same rule counts. Helium is lighter than oxygen and nitrogen.
What nuclear process coverts helium and hydrogen gases from lighter to heavier elements?
The process is called fusion; hydrogen nuclei are fused together to make helium. At much higher temperatures and pressures, the helium can fuse into carbon and nitrogen and oxygen.
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.
Is oxygen lighter than helium?
no. If it was, we would have oxygen balloons instead of helium balloons.
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
Does helium have smaller particles than nitrogen or oxygen?
Helium has smaller particles than nitrogen or oxygen. Helium atoms are smaller in size, as they have fewer protons and neutrons in their nucleus compared to nitrogen or oxygen atoms. This smaller size allows helium atoms to move more freely and escape into the atmosphere, which is why helium is a lighter gas.
Is there anything lighter than oxygen?
In fact there are seven elements lighter than oxygen: hydrogen, helium, lithium, beryllium, boron, carbon and nitrogen.
What is lighter oxygen or nitrogen?
Nitrogen is lighter than oxygen. The atomic weight of nitrogen is approximately 14, while the atomic weight of oxygen is approximately 16.

Is air lighter than heluim?
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.
Why is it that the nitrogen have greater amount than oxygen?
nitrogen is lighter than oxygen
What gases has lowest density Argon or Oxygen or Helium or Nitrogen?
Helium
What happens when water vapor is lighter than nitrogen or oxygen?
Water vapor is a gas so it is in the air. Nitrogen and nitrogen are in the air too, but there is more nitrogen than anything in the air. I believe it rises because it is lighter, like a balloon filled with helium.
What is and example of a gas?
nitrogen,Helium,oxygen
Is and example of a gas?
nitrogen,Helium,oxygen
Is helium lighter than nitrogen?
Yes, helium is lighter than nitrogen. Helium is the second lightest element, while nitrogen is a bit heavier due to its molecular structure. In fact, helium is the lightest noble gas and is commonly used in balloons for this reason.
