Can One Electron Make Two Transitions in a Row?

Click For Summary

Discussion Overview

The discussion revolves around the question of whether a single electron can make two transitions in a row in the context of photon emissions from excited atomic hydrogen. Participants explore the implications of photon energies and atomic energy levels, considering various scenarios involving multiple atoms and transitions.

Discussion Character

  • Homework-related, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests that the three photon energies (12.1 eV, 10.2 eV, and 1.9 eV) must originate from a single atom, based on their calculations.
  • Another participant requests the first poster to show their working and reasoning to understand the conclusion better.
  • A different participant provides energy levels for hydrogen, indicating that if an electron de-excites from the M level, it could account for the observed photon energies, supporting the idea of a single atom.
  • There is a question about the number of electrons in each atom, leading to a clarification that there is one electron per atom.
  • One participant proposes that the answer could be three atoms, reflecting on the number of electrons and their transitions.
  • A later reply questions the feasibility of one electron making two transitions in a row, introducing a critical aspect of the discussion regarding electron behavior.

Areas of Agreement / Disagreement

Participants express differing views on whether the photons originate from a single atom or multiple atoms, and there is no consensus on the possibility of one electron making two transitions in a row.

Contextual Notes

The discussion includes assumptions about atomic energy levels and the behavior of electrons during transitions, which may not be fully resolved. The implications of photon energies and the number of atoms involved remain open to interpretation.

Who May Find This Useful

Students studying atomic physics, educators looking for examples of atomic transitions, and individuals interested in the behavior of electrons in quantum systems may find this discussion relevant.

Homework Statement



Three photons coming from excited atomic hydrogen sample are picked up. Their energies are 12.1 eV, 10.2 eV and 1.9 eV. These photons must come from?
A)two or three atoms
B)single atom
C)three atoms
D)two atoms

The Attempt at a Solution


By solving it i got single atom but it is not the answer...

Please show your working and reasoning.

In a hydrogen atom energy of k level is -13.6eV
L level is -3.4eV
M level is -1.5eV
Now if electrons dexcite from M level then there is possibility for the three values of the energy of photons released... That's the reason I got only single atom

How many electrons are there in each atom?
 
One. Electron in each atom ... So. I think answer will be three ... I didnt think of the number of electrons but i thought of only possibilities
 
Is it possible for one electron to make two of the transitions in a row?
