Oxygen
Helium, argon, and neon are noble gases with different atomic numbers: helium (2), neon (10), and argon (18). They vary in terms of their densities, boiling points, and chemical reactivity. Neon has the lowest boiling point and argon has the highest atomic weight among the three.
Yes, argon is heavier than air. Argon has a higher density than air, so it will sink below the air in the atmosphere.
Yes, argon is heavier than carbon dioxide. Argon is a noble gas that is denser than the diatomic molecule carbon dioxide, which consists of one carbon atom and two oxygen atoms.
No, helium and argon are not the same. They are two different elements on the periodic table with different properties. Helium is a noble gas with the atomic number 2, while argon is also a noble gas but with the atomic number 18.
Niether. In 2015, the largest known atom belonged to ununoctium.
Helium
argon is a component of "air" and as such air cannot be lighter than air, only more or less dense, however, judging from atomic masses, yes argon is heavier than nitrogen, oxygen, helium, and hydrogen, but depending on pollutants and other gases (CFC's, HCFC's, etc.) the compound that is air can vary slightly in mass.

Gases that are heavier than oxygen include nitrogen, argon, krypton, xenon, and radon. These gases have greater atomic or molecular weights than oxygen, making them heavier.
Argon is heavier than oxygen. The atomic mass of argon (Ar) is around 40 g/mol, while the atomic mass of oxygen (O) is around 16 g/mol.

What is air but a mixture of gasses? Nitrogen, oxygen, helium and a little argon.
Argon and Helium are part of the noble gasses family.
