Does argon exist as a diatomic molecule?
No, it is a nobel gas. It will just be Ar.
What are the similarities between atoms and molecules?
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.
What is the molecular formula for argon?
