Atomic Number. :)
Argon is an element and all the atoms in argon are argon atoms.
Yes
Yes, all atoms of argon have the same atomic number, which is 18. Atomic number refers to the number of protons in the nucleus of an atom, and for argon, it always remains constant at 18.
No. Neon atoms and Argon atoms have different atomic numbers. Which means they have different numbers of protons.
Argon gas is made up of individual atoms of argon. It is a noble gas and exists as single atoms rather than as molecules.

Avogadro's number is is 6.0221409 *10^23. It is the same number for all atoms or molecules.
Atoms argon-40, potassium-40, and calcium-40 all have 40 protons, but differ in the number of neutrons in their nuclei. They are all stable isotopes, with no natural radioactivity.
Argon-40, potassium-40, and calcium-40 all have 40 protons and electrons in their atoms, but they have different numbers of neutrons. They are all stable isotopes, although potassium-40 is radioactive and undergoes decay to form argon-40.
Yes, argon is made up of individual argon atoms. Argon is a noble gas that exists as a monatomic gas, meaning it is composed of single atoms.

2.3 × 1024 atoms of Ar
They have the same mass.
Argon is a noble gas, and is present as discrete atoms . this is called monoatomic
