How Would a Change in Electron Spin Alter the Identity of Noble Gases?

Click For Summary

Homework Help Overview

The discussion revolves around the hypothetical scenario of electrons having a spin number of \(\frac{3}{2}\) instead of the conventional \(\frac{1}{2}\). Participants explore how this change might affect the identity of noble gases, which are typically characterized by fully filled electron shells.

Discussion Character

  • Conceptual clarification, Assumption checking, Exploratory

Approaches and Questions Raised

  • Participants question the implications of altered electron spin on the quantum mechanical properties of noble gases. They discuss the relationships between quantum numbers and the filling of electron shells, seeking to understand how the new spin state might influence the definition of noble gases.

Discussion Status

The discussion is ongoing, with participants raising questions about the significance of electron spin in the context of noble gases. Some hints have been provided regarding the characteristics of noble gases and the filling of electron shells, but no consensus or clear direction has emerged yet.

Contextual Notes

Participants are considering the implications of a theoretical change in electron spin, which may not align with established quantum mechanics. The exploration is constrained by the need to adhere to the original homework prompt and the speculative nature of the discussion.

Homework Statement



Suppose that electrons had a spin number of \frac{3}{2} instead of \frac{1}{2}

That is, they have ould magnetic spin states of S_{z} = \frac{-3}{2}\hbar , \frac{-1}{2}\hbar , \frac{+1}{2}\hbar , \frac{+3}{2}\hbar

Which elements would be the "new" noble gases in this case?

Homework Equations



"real" electron spin = + 1/2, - 1/2.

Noble gases are in the group of Helium (Neon, Argon, etc.)

The Attempt at a Solution



I figured it was going to be easy because, looking at the dependence of the other 3 quantum numbers on each other, it would reveal the solution quickly. The dependence I'm referring to is n = 1, 2, 3, ...
l = 1, 2, n-1... and so on..

I can't find a dependence this clear with the spin number though.

How do you build up the electron stucture for helium & neon
Does a pattern reveal?
