The orbital is the probable location of the electron of an atom.
Always remember the difference between Bohr and wave-mechanical model in terms of electrons!
Your questions answer is Electron!
But you should also know Bohr said electrons are in orbitals in a fixed proportion, but modern wave mechanical disagrees with this and said electrons are arranged in a very complex random proportion in a region called orbital!
Hope this helped
have a smiley day (:
