Doesn't the atom in ground state radiate?

Click For Summary

Discussion Overview

The discussion centers around whether an atom in its ground state radiates energy, exploring theoretical perspectives and interpretations of atomic behavior in relation to thermal radiation. The scope includes conceptual understanding and theoretical implications.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant asserts that an atom in the ground state does radiate energy and balances this with energy absorbed from heat radiation, questioning the conventional view presented in textbooks.
  • Another participant challenges this viewpoint, suggesting that the linked source contains misinformation and encourages reliance on established textbooks.
  • A subsequent reply emphasizes that while an atom in the ground state does not radiate, it can absorb energy from its environment, leading to excitation and subsequent radiation from an excited state.
  • A later response indicates that discussions on theories outside professional scientific literature are not permitted, leading to the closure of the thread.

Areas of Agreement / Disagreement

Participants express disagreement regarding the radiation of atoms in the ground state, with some supporting traditional textbook views and others proposing alternative interpretations. The discussion remains unresolved as differing perspectives are presented without consensus.

Contextual Notes

The discussion references theoretical claims that may not align with established scientific literature, and the validity of the linked source is contested. There are implications regarding the definitions of ground and excited states that are not fully explored.

According to textbooks, an atom in ground state doesn't radiate. Yet I got some other idea after reading Wu Ta-you's theoretical physics book. I hold the viewpoint that the atom does radiate, and at the same time it absorbs energy from heat radiation in its environment. The energy it radiates out and absorbs in balance. Am I correct or am I wrong? I eagerly appreciate everyone's reply. (For details, please visit <deleted>)

The site you linked to is full of nonsense. Believe your textbooks.

Thanks for your reply, though it wasn't what I expected.
Don't you think in a real world, the atom will absorb energy from the heat radiation in its environment?
 
An atom in the ground state can absorb energy from the environment including thermal radiation. Once it has done so it will be excited and will no longer be in the ground state. An excited atom can radiate and go to a lower energy state, but an atom in the ground state cannot radiate since there is no lower energy state.

We do not discuss topics that are outside the professional scientific literature, so we cannot discuss the incorrect theory in your deleted link. Thread closed.
