By allowing the positive ions to pass through an electric field and thus giving them a certain velocity, it is possible to distinguish them from the neutral, stationary atoms.
Johannes Stark
I think there's a little bit of sizzling here. Honestly, I can feel it. The ions are flying back and forth.
Regis Philbin
Thus at the beginning of 1906 it seemed to be established that the emitters of the spectral series of chemical elements are their positive atomic ions.
Johannes Stark
We can in fact first place the beam of rays of moving positive atomic ions in a plane perpendicular to the axis in which we see the spectral lines emitted by them.
Johannes Stark
We were on the dark side of the Earth when we started to see outside the window this soft pink glow, which is a lot of little angry ions out there going very fast. We were hitting them very fast.
