i would say that maybe the transistor includes one atom of phosphorus - it doesn't comprise of one atom and that's it.
It would take many atoms to provide conductors and insulation.
My hypothetical device below, needs at least 15 atoms. My Hypothesis
I think that it might be an "Electro-Mechanical FET" (for want of a better description).
The yellow blocks represent conductors (probably Gold).
The red block represents the Phosphorus atom.
The pink/purple lines represent an electric field.
It is constructed so that the Phosphorus atom normally sits at one end ("0"
When a charge is applied to the conductor, the Phosphorus atom moves to the other end, bridging the conductors at that end ("1"
When the charge is removed the Phosphorus atom returns to the other end ("0"
