SUMMARY

The discussion focuses on the electron configurations of elements and their placement in the periodic table, particularly in hypothetical universes with altered quantum mechanics. Key points include the exploration of three possible spin states for electrons and the implications of the l quantum number extending to n. Participants express confusion regarding the identification of exceptions in electron configurations, particularly in the d-block elements, and how these changes affect the classification of noble gases.

PREREQUISITES
  • Understanding of electron configurations and the periodic table
  • Familiarity with quantum mechanics concepts, including spin states
  • Knowledge of quantum numbers, specifically l and n
  • Basic grasp of d-block elements and their exceptions
NEXT STEPS
  • Research "Quantum mechanics and electron spin states" to understand implications on atomic structure
  • Study "Quantum numbers and their significance in electron configurations" for deeper insights
  • Explore "Exceptions in d-block electron configurations" to identify specific cases
  • Investigate "Noble gases and their electron configurations" to clarify their classification
USEFUL FOR

Students of chemistry, physicists interested in quantum mechanics, and educators looking to explain complex atomic structures and electron configurations.

Which elements have electron configurations different from what the periodic table predicts? I have the d-block, but i don't know how/where to get the rest.


Suppose in another universe, everything about atomic structure is the same as in our universe BUT there are 3 possible spin states for an electron in an orbital(up, down, and side) instead of two. How would this change where the elements are in the periodic table? which are the noble gases?

In another universe, everything about quantum mechs and atomic structure is the same as in our universe excpet that the l quantum number can take values from 0 up to the value of the n quantum number. How would this change where the elements are on the periodic table? Which are the noble gases?

thanks

This looks like homework (and a double post)

What are your thoughts, sara ?
 
For the first one, I don't know how you can determine which ones are exceptions. I found a list of the d-block and i know how to explain them, but i just don't understand how you know which are the exceptions i guess.

For the next two, I don't understand how it ties into the periodic table.
