as we know that atom does not exist in free state,why does monoatomic element exist?

Answer 1

monoatomic elements exists free nature becoz they never react with other element.
for example the gold (Au) or u can called it aurite,
it sometimes found in free state . it is also called as nuggets.

Answer 2

What are you asking?
You seem to be contradicting yourself saying that lone atoms cannot exists, then asking why monoatomic elements exist.

Atoms can exist by themselves. A single atom is the smallest particle which still retains the chemical properties of the particular element. Some atoms can be found free, unbounded, in their natural states. Take the Nobel gasses for instance, these atoms never (or hardly ever) bond with other atoms...they exist as a monoatomic gas.

Answer 3

Monoatomic element exists due to their outershell electrons are filled.And atom may exist in free state as of neon,argon and noble elements.It is a misperception that atom does not exists in free state.It may exist.

Answer 4

Inert gas molecules are monatomic; there isn't enough attraction between atoms to form diatomic gas molecules, because you've got full valence electron shells. More reactive gases like oxygen and nitrogen form diatomic covalent gas molecules. You've got two identical atoms sharing valence electrons.

Answer 5

because their octet is completed and they are inert because of that
