Yes, hydrogen is always a terminal atom.

Explanation:

Hydrogen has only one electron, so it can form a single covalent bond with only one other molecule. It can't form double bonds and it can't bond with more than one molecule because it doesn't have two electrons to share.

Because hydrogen can only bond with one other molecule, it will never be anything other than a terminal atom.
