Are Di-Atomic Molecules spherical?

Click For Summary

Discussion Overview

The discussion revolves around the shape of diatomic and polyatomic molecules, questioning the common assertion that molecules are spherical. Participants explore the implications of atomic structure and electron configuration on molecular shape, considering both theoretical and practical perspectives.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • One participant suggests that while monatomic molecules may be considered spherical, diatomic and polyatomic molecules consist of multiple atoms and thus cannot be truly spherical.
  • Another participant points out that certain configurations, such as buckyballs, can be spherical, but also notes that atoms themselves may not necessarily be spherical depending on their electron configuration.
  • A follow-up question asks what other shapes atoms can take beyond spheres, indicating a search for clarity on atomic structure.
  • One participant mentions that electron clouds around atoms can have various shapes due to the repulsion between electrons, implying that molecular shapes are complex and not strictly spherical.
  • Another participant states that while molecules may not exhibit spherical symmetry, diatomic molecules can sometimes be approximated as round in specific contexts, such as in the treatment of gases.

Areas of Agreement / Disagreement

Participants express differing views on the shape of molecules, with no consensus reached. Some argue for the spherical nature of certain configurations, while others emphasize the complexity and variability of molecular shapes.

Contextual Notes

Participants highlight the challenges in defining molecular shape due to the presence of empty space within atoms and the influence of electron configurations on the perceived shape of molecules.

It is usually said that molecules are spherical in shape, that is what we learn from our textbooks. May be what they are saying is true but only in the case of a monatomic molecule. If one considers a diatomic molecule there are two atoms that means two spheres and if it is polyatomic there is no doubt there are many spheres attached to one another. If that is the case polyatomic molecules are never really spherical! Please clear my this confusion.

There are configurations of atoms that are spherical, a bucky ball for example. Atoms don't have to be spheres either, it depends on how many electrons are in their outer most shell.

Then what else is the structure that an atom can have other than a sphere?
 
Atoms and molecules are mostly empty space. It is hard to define a shape.
 
The angle dependence of atomic orbitals are spherical harmonics.

Molecules do not have spherical symmetry. But diatomics can be often treated as round things, for example as a Vanderwaals gas.
