Where do the electrons go in a decay process?

Click For Summary

Discussion Overview

The discussion revolves around the behavior of electrons during alpha decay processes, specifically focusing on the fate of electrons associated with the daughter nucleus and the alpha particle. It includes conceptual exploration and speculative reasoning regarding electron distribution post-decay.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant notes that the alpha particle does not have electrons orbiting around it during alpha decay, questioning the status of electrons in the remaining daughter nucleus.
  • Another participant states that the daughter atom is initially ionized with a charge of -2.
  • A later post humorously references the concept of an "Electron Graveyard," suggesting a whimsical take on the fate of electrons in decay processes.
  • Further elaboration indicates that while the alpha particle initially lacks electrons, it is suggested that alpha particles eventually pick up electrons from other sources, leading to the formation of neutral helium gas over time.
  • There is speculation that the electrons that neutralize the daughter nucleus may not come directly from the ionized atoms left behind but rather from a redistribution of electrons in the surrounding environment.

Areas of Agreement / Disagreement

Participants express differing views on the specifics of electron behavior during decay, with no consensus reached on the exact mechanisms or sources of electrons post-decay.

Contextual Notes

The discussion includes assumptions about electron behavior and the nature of ionization that are not fully resolved, particularly regarding the sources of electrons that neutralize the daughter nucleus.

In an alpha decay the alpha particle doesn't have any electrons orbiting around it, right? But what about the remaining daughter nucleus? And where do the electrons go if they go?
 
Physics news on Phys.org
The daughter atom is initially ionized (-2).
 
Aha. Thanks!
 
"Where do the electrons go in a decay process?"

To that which many have sought but none have found - the legendary Electron Graveyard.

Littered with fossilized strings, of course. :biggrin:

Not initially. But I understand that one of the original pieces of evidence that alpha particles are really helium nuclei was that if you seal an alpha source into an airtight container, when you open the container later, you find some helium gas in it. So the alphas eventually pick up electrons. These are probably not directly from the ionized atoms that they left behind, but other electrons eventually redistribute themselves to make all the atoms neutral again.
