No - chlorine exists as Cl2 and is thus diatomic.
No, sodium is an element that exists as single atoms and not as molecules. Sodium is a monoatomic element because it consists of single atoms.
Yes. Argon is chemically inert due to the presence of completely filled orbitals. So it exists as a monoatomic species.
No, it is most commonly regarded as tetratomic (tetra=4) molecule: P4
No. argon is a monoatomic element. It does not combine with other elements or with itself.
No, copper is not a monoatomic element. It is a transition metal with the chemical symbol Cu and atomic number 29, meaning it consists of atoms bonded together rather than existing as single atoms.
Copper is a monoatomic chemical element.
The valence of a monoatomic chlorine ion is 1 and its charge is -1.
No, sodium is an element that exists as single atoms and not as molecules. Sodium is a monoatomic element because it consists of single atoms.
no. it is monoatomic
This is a monoatomic ion.
No, krypton is a monoatomic element.
Yes. Argon is chemically inert due to the presence of completely filled orbitals. So it exists as a monoatomic species.

Chlorine is an element.
No. argon is a monoatomic element. It does not combine with other elements or with itself.
Helium is not a compound, it is an element.
pure, monoatomic not bound to any other element
