Discussion Overview

The discussion revolves around the stability of atomic nuclei and the role of mass energy in this context. Participants explore concepts related to nuclear decay, fusion, and fission, examining how mass energy changes influence stability and energy states.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions how the loss of mass energy contributes to nuclear stability.
  • Another participant argues that the notion of mass energy loss aiding stability is not universally true and cites decay chains leading to stable particles with no decay modes.
  • A participant inquires whether nucleons lose mass energy during decay reactions.
  • It is noted that the nucleus loses mass overall during decay processes, including the mass of emitted particles.
  • A discussion point is raised about fusion and fission, questioning if mass energy loss during these processes reduces the potential energy of the resulting nuclei.
  • One participant suggests that while total energy decreases, the concept of potential energy may be misleading in this context.
  • A later reply expresses gratitude for the clarification provided.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between mass energy loss and nuclear stability, indicating that multiple competing perspectives remain without consensus.

Contextual Notes

The discussion includes unresolved assumptions about energy concepts and the implications of mass energy changes in various nuclear processes.

How does the nucleons losing some of its mass energy help in making it more stable?
 
Physics news on Phys.org
It does not "help", and it is not true in general.
If you follow a decay chain long enough, you will always reach some particle which has no possible decay mode any more simply because it does not have enough energy (the decay products would have more mass than the particle itself, therefore the decay is impossible).
 
So does nucleons lose mass energy so that a decay reaction??
 
The nucleus in total loses mass - even if you include the mass of emitted alpha particles or electrons for alpha and beta decays, respectively.
 
But suppose a case of a nuclei formatoon like fusion or fission. Now if some mass energy is lost in the process of formation of the new nuclei in the form of heat, isn't it suppose to decrease the potential energy of the nuclei?
 
It decreases the total energy. "Potential energy" is a problematic concept here because you can easily mix it with other concepts.
 
Oh ok thanks a lot.
