Helium exists as a monatomic gas, with Atomic Mass of 4.0. Thus any gas with a molecular mass higher than 4.0 would be heavier than helium. Hydrogen is the only gas that is lighter than helium; all others are heavier than helium.
What else can I help you with?
Why helium is lighter than gas?
Helium is a gas, so it is not lighter than gas. It is like asking why is water heavier than liquid. Helium is less dense than all other gases except hydrogen, because it has an atomic weight of 4.
Which is heavier hydrogen or helium?
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
Is helium lighter or heavier?
Helium is lighter than air
Is air heavy than helium?
Yes. air is heavier than helium.
Are heavier atoms heavier than helium atoms?
yes.
What is An inert gas with a greater atomic mass then helium?
Helium is the lightest noble gas, so neon, argon, krypton and xenon are all heavier noble gases. Radon's also a noble gas and it's heavier than helium, but it's radioactive so is it really inert?
What is heavier nitrogen or helium?
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
Is a helium balloon heavier than air filled balloon?
No. Helium is lighter than air
What is lighter than helium but heavier than air?
hydrogen
How is oxygen gas heavier?
Oxygen gas is considered heavier than other gases (like nitrogen and helium) because the oxygen molecule (O2) has a higher molecular weight due to its two oxygen atoms bonded together. This higher molecular weight causes oxygen gas to be denser and therefore heavier than some other gases.
How many times heavier is a sulfur atom than a helium atom?
A sulfur atom is about 32 times heavier than a helium atom. This is based on the atomic masses of sulfur (32 amu) and helium (4 amu).
Is helium lighter or heavier than hydrogen?
Heavier but safer. Look what happened to the Hindenburg:(
