Question

What are diatomic molecule examples?

Answer 1

Apart from the Noble gases, ALL the elemental gases are bimolecular.

Explanation:

So what are the molecular gases: dinitrogen, dioxygen, fluorine and chlorine. There is also a `Li_2` species, but you cannot put this into a bottle. All of the halogen elements, i.e. `X_2`, are bimolecular.

I have given you bimolecular elements; you will hve to supply some bimolecular compounds; the hydrogen halides are a start.
