Helium
Helium is lighter (less dense) than oxygen & nitrogen.
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.
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.
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.
no. If it was, we would have oxygen balloons instead of helium balloons.
Helium is lighter (less dense) than oxygen & nitrogen.
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.
In fact there are seven elements lighter than oxygen: hydrogen, helium, lithium, beryllium, boron, carbon and nitrogen.
Nitrogen is lighter than oxygen. The atomic weight of nitrogen is approximately 14, while the atomic weight of oxygen is approximately 16.

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.
nitrogen is lighter than oxygen
Helium
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.

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.
