Zero. That’s it. A hydrogen ion has exactly zero electrons. It’s just a lonely proton, all by itself.
Think of it like a banana that has been peeled. The peel is the electron. The banana is the proton. The hydrogen ion is the banana without the peel—naked, sad, and totally charged.
When a hydrogen atom loses its only electron, it becomes a hydrogen ion. It’s the most stripped-down, minimalist thing in the universe.
