Discussion Overview

The discussion centers around Moseley's Law, specifically the reasoning behind the use of (Z-1) instead of just Z in the equation. Participants explore the implications of electron-electron repulsion in atomic transitions and the historical context of Moseley's initial thoughts on screening effects.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions why Moseley's Law uses (Z-1) rather than Z.
  • Another participant references the Wikipedia page that attempts to explain the significance of (Z-1) and asks for clarification on specific aspects.
  • A third participant cites the Wikipedia explanation regarding electron-electron repulsion and expresses uncertainty about deriving specific values of 1 and 7.6.
  • It is noted that Moseley initially attributed the phenomenon to screening effects.

Areas of Agreement / Disagreement

The discussion remains unresolved, with participants expressing uncertainty and differing interpretations of the concepts involved.

Contextual Notes

Participants have not reached consensus on the derivation of values or the implications of electron-electron repulsion in the context of Moseley's Law.

That page attempts to explain the Z-1. What part of it are you having trouble with?
 
wiki states it is "predominantly a consequence of the difference of the value of the electron-electron repulsion in the initial and final states of the atom that undergoes the x-ray transition"

but I'm not sure how we can derive the values of 1 and 7.6
 
so initially Moseley thought it was due to screening
