Discussion Overview

The discussion revolves around identifying the most stable structure across various contexts, including physical shapes, atomic arrangements, and crystal structures. Participants explore different interpretations of stability and structure, leading to a range of examples and criteria for stability.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants propose that a low, heavy rectangle is the most stable structure due to its low center of gravity, while others argue that a triangle is the strongest structure because it distributes pressure effectively.
  • One participant mentions that the BCC crystal structure may have the lowest energy, but this is contested as it may not apply universally across different materials.
  • Another participant suggests that stability can depend on the context, asking for clarification on whether the discussion pertains to subatomic, atomic, or macroscopic levels.
  • Some participants highlight that noble gases like neon have stable atomic structures due to full electron shells, while diamond's lattice structure is noted for its strength and stability.
  • There is a suggestion that the stability of structures can vary significantly depending on the specific material or context being considered.

Areas of Agreement / Disagreement

Participants do not reach a consensus on what constitutes the most stable structure, as multiple competing views and interpretations of stability are presented throughout the discussion.

Contextual Notes

Participants express uncertainty regarding definitions of stability and structure, and the discussion includes various levels of analysis, from subatomic to macroscopic, which may affect conclusions drawn.

Who May Find This Useful

This discussion may be of interest to those exploring concepts in structural stability, material science, and atomic theory, as well as individuals curious about the properties of different structures across various scales.

Most stable structure ??

Hi
Could anyone tell me which/what is the most stable structure? And Why??

Thanks a lot

The most stable?

A really low, and heavy rectangle. Why? Because it has a really low center of gravity, and it cannot tip over easily.

But, the strongest?
A triangle. Why? Because when you put pressure on any part of the triangle, the pressure is divided up around the 3 sides, making the tensile strength increase greatly.

Depends what you mean by 'stable' and 'structure'.
 
There is only one meaning for stable and structure, in this context:
Stable- –adjective, -bler, -blest.
not likely to fall or give way, as a structure, support, foundation, etc.; firm; steady.
Structure- –noun
mode of building, construction, or organization; arrangement of parts, elements, or constituents: a pyramidal structure.

The BCC crystal structure appears to have the lowest energy, IIRC. But, the various hexagonal packings are also quite stable.

On what level - subatomic, atomic, crystal/molecular, grain, product, building, moon, planet, star, . . . . ?

This isn't generally true. It applies to iron at room temperature, for example, but not to aluminum, copper, gold, silicon, carbon, tungsten...

Ahhh. Sorry about that post there, I did not consider the question in the right context.
 
a sphere?

ok
let me rephrase the question...
what is the most stable structure at sub atomic,atomic and marcoscopic level..??
 
  • #11
Well group 0/8 atoms such as neon have the most stable atoms because their outer shell is full of electrons and they can't react with other elements. I guess the strongest structure would be the lattis structure of diamond which has 4 bonds with other atoms I think.

What about Diamond? It's F[ace] C[entered] C[ubic], if I'm not wrong.

Isn't that pretty stable, considering its high melting temperature?
