Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.
Methane is CH4 and argon being an inert element is just Ar.

No, it is a nobel gas. It will just be Ar.
They are similar in the way thatthey are both considered individual units of a substance. However, at times, a molecule is an atom. For example, Argon (Ar) a noble gas is an atom, but it is also a molecule as it already has a full valence shell, thus it does not need to bond with other elements.
Argon is an element, not a molecule, and as such does not have a molecular formula, but rather a symbol - "Ar".
