There is one atom in argon. Argon is a "noble gas", which means that it occurs independently. This is true for all of the atoms on the final column of the periodic table. http://en.wikipedia.org/wiki/Noble_gas
2.3 × 1024 atoms of Ar
3,50 moles of argon equal 21,0774929995.10e23 atoms.
atoms of argon are heavier than atoms of nitrogen
No. Neon atoms and Argon atoms have different atomic numbers. Which means they have different numbers of protons.
There are approx 1.19*10^24 atoms.
