Discussion Overview

The discussion revolves around the significance of the distance between two ionic cores as they approach each other. Participants explore the implications of this distance change in the context of bonding and electromagnetic interactions.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant seeks clarification on the physical phenomena occurring as the distance between two ionic cores decreases and its significance.
  • Another participant questions whether the inquiry pertains to the changes in the electromagnetic field as the ions approach or the reasons for their proximity.
  • A different viewpoint suggests that the interaction involves the formation of bonding orbitals from non-bonding orbitals, although this does not lead to a solid structure.
  • A reference to a chemistry book is provided for a more straightforward explanation of bonding in extended structures.

Areas of Agreement / Disagreement

Participants express differing interpretations of the original question, indicating a lack of consensus on the specific aspects being discussed regarding ionic cores and their interactions.

Contextual Notes

The discussion lacks clarity on the assumptions behind the questions posed and the specific definitions of terms like "bonding orbitals" and "solid." There are unresolved aspects regarding the nature of the interactions as the distance changes.

Given two ionic cores, i and j, can someone please explain what it is that's happening as the distance between them decreases? What is its significance?

It is difficult to know what exactly you are asking here. Are you asking why, as the two ions gets closer, the field changes? Isn't this just a standard E&M problem?

Or are you asking what would cause the two ions to be closer?

All I can see is that they are forming bonding orbitals from non-bonding orbitals. But that itself does not make any solid.
