What else can I help you with?
What would happen if you poured liquid helium into liquid nitrogen?
If you pour liquid helium into liquid nitrogen, the helium will not mix with the nitrogen and will instead form separate layers. Helium is lighter than nitrogen and has a lower boiling point, so the helium will tend to float on top of the 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.
How much lighter is hydrogen compared to helium?
Hydrogen is about 7 lighter than helium.
What is heavier nitrogen or helium?
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
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.
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.

Is there anything lighter than oxygen?
In fact there are seven elements lighter than oxygen: hydrogen, helium, lithium, beryllium, boron, carbon and nitrogen.
Is a tank of helium lighter than a empty tank?
No, helium has weight, but it rises when its in an expandable container such as a balloon because it is lighter than the nitrogen rich atmosphere but inside of a rigid container the helium can only add weight. (see the mythbuster's episode about the helium football)
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 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 helium lighter than nitrogen?
Your question is wrong because hydrogen is the lightest gas but other than that its the lightest nobel gas, and that's just cause its atoms don't have much to them, and neither dose its molecules. With an atomic mass of 2, its the second lightest substance there is, and therefore attracted by gravity the second least of anything, so its gonna be ontop of all other matter (exept hydrogen which has the atomic mass of one)
Which is lighter oxygen helium or nitrogen?
Helium is the lightest of the three gases, with an atomic mass of 4 compared to 16 for oxygen and 14 for nitrogen.
Is helium lighter or heavier?
Helium is lighter than air
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.
Is helium lighter than earth?
yes. helium is lighter than earth or even air.
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.
