With an anode of mercury, mercury ions could well migrate to the cathode in an evacuated tube. Vaporising a pool of mercury with a positive potential (an anode) and striking an arc would cause electrons to move one way (much faster)- to the anode and mercury ions to move the other way (much slower) - to the cathode.

If you are talking about atoms as an electric current, the answer to the original question has to be no. Atoms are neutral. A current carrier needs to be a charged species such as an electron or an ion (+ve or -ve, elemental or molecular).
