No. Helium is lighter than air
Helium is lighter than air because of atomic mass. Helium is element number two, whereas oxygen is element number 8. Oxygen has an atomic mass of 16, and helium has a mass of 4, so helium is 4 times lighter than air. (Atomic mass is the total mass of protons, neutrons, and electrons in a single atom.)
No, carbon dioxide is heavier than helium. Carbon dioxide has a molecular weight of about 44 g/mol, while helium has a molecular weight of 4 g/mol. This means that helium is lighter than carbon dioxide and will rise above it in the presence of air.
Helium is typically used to make balloons fly up in the air because it is lighter than air and creates lift. Hydrogen is also lighter than air and can be used, but it is flammable. Carbon dioxide is heavier than air and would cause a balloon to sink.
Neon has 8 more protons and 8 more electrons than helium. It's heavier, but still lighter than air.

No. Helium is lighter than air
yes, anything with a lower atomic number would be lighter, for example, helium is lighter than air, which is why balloons float when filled with helium... the lighter substance rises above the heavier....
Because, carbon dioxide is heavier than air whereas helium is lighter than air.

Yes. air is heavier than helium.

No, helium has the second lowest density out of all the elements and with Hydrogen having the smallest density but it not being in the air it means the canister of air is heavier.
yes. helium is lighter than earth or even air.
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.
