The article currently states:
"If the
ion gains electrons from its environment, the alpha particle can be written as a normal (electrically neutral) helium atom 4
2He."
This is unclear. How could the species still be an alpha particle if it has gained electrons to become an ordinary (neutral) helium atom?

The article says: They then caused an electric spark inside the tube, which provided a shower of electrons that were taken up by the ions to form neutral atoms of a gas. This sounds a little strange to me. The alpha particles won't be a gas until they get electrons, which they likely will as soon as they hit the wall. As long as they don't go too far into the fall. Do they then stick? You can't get a spark through vacuum, but only through gas. It might be that heat is needed to get them off the wall, though. Gah4 ( talk) 00:27, 2 October 2020 (UTC)
I rewrote the name section to give the origin of the name "alpha particle" and the connection to doubly ionized He atoms.
The previous section had no references and it has several claims about common usage (which probably cannot be verified unless some authority chose to say such). I suspect that when ever radioactivity is the source, the result is called "alpha particle" until the particle picks up two electrons and acts like a gas molecule, Helium. I doubt anyone calls the radiation product "doubly ionized Helium". On the other hand, if we start with Helium and ionize it, then yes we call it "doubly ionized Helium"; then it's not an alpha particle. The fact that these two products, from very different origins, have the same nucleons would not change the name used. I'll be on the look out for a reference to this effect.
