The external shell of electrons is completely filled.
Most single atoms are unstable and must undergo a chemical reaction in order to become stable. The noble gases, however, can exist as single atoms, because they have filled valence shells and are therefore stable on their own.
Diatomic elements, such as hydrogen, nitrogen, oxygen, and halogens, are not found in nature as single atoms because they are more stable in their diatomic molecular forms. This stability arises from the covalent bonds formed between two atoms of the same element, which lowers the energy of the system. Single atoms are generally more reactive and less stable, leading them to quickly combine with other atoms to form diatomic molecules. As a result, these elements predominantly exist in their diatomic state in the natural environment.
Helium, neon, and argon are the only elements that exist in nature as isolated atoms, due to their stable electronic configurations that do not readily form chemical bonds with other elements. These elements are known as noble gases for their inert nature.

Why were you not aborted??
No. It is a Atomic element because it exist in nature with single atoms as their basic unit.

Yes
Argon is monoatomic in nature because it is a noble gas with a full valence shell of electrons. This stable configuration makes it energetically favorable for argon atoms to exist as single atoms rather than bonding with other atoms to form molecules. As a result, argon remains as individual atoms in its natural state.
It has four silicon atoms.
