Copper is a monatomic ion.
Argon is a monoatomic element.
Yes. Argon is chemically inert due to the presence of completely filled orbitals. So it exists as a monoatomic species.
No - chlorine exists as Cl2 and is thus diatomic.
Helium is a chemical element, not a compound; also helium is monoatomic.
