Yes it can. helium will not react chemically with copper.
It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.
No. Carbon dioxide is heavier than helium.
Hydrogen, helium, small amounts of lithium. No heavier elements. Lots of the mysterious dark matter.Hydrogen, helium, small amounts of lithium. No heavier elements.

No. Helium is lighter than air
Helium is heavier.
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
Helium is lighter than air
yes.

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.

Heavier but safer. Look what happened to the Hindenburg:(
no, steel is heavier
density of copper = 8930 kg/m^3 & density of brass = 8700 kg/m^3 copper is heavier
