Which molecules are pure elements?

Well none since molecules are a group of two or more atoms electrically bonded with one another. However, there are gases that does not naturally bond due to their stability and can be found in nature as pure elements. But these are not considered as molecules.
(By the way, these gases are the noble gases that can be found on the last column of the periodic table)

Pure elements consist of molecules made entirely of one type of atom. These molecules can be diatomic, like O₂ and N₂, or polyatomic, like S₈. They are characterized by their unique properties and cannot be broken down into simpler substances by chemical means.
