Discussion Overview

The discussion revolves around the electronic configuration of a hypothetical chemical element with an atomic number of 2046. Participants explore the application of the Aufbau principle and quantum numbers in determining the valence electron configuration, despite the element's presumed instability.

Discussion Character

  • Homework-related, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant asks for the electronic configuration of the last two valence layers for an element with atomic number 2046, referencing the configuration for iron (Fe) as an example.
  • Another participant questions whether the inquiry is related to homework, suggesting it resembles standard homework questions that appear frequently on the forum.
  • A participant clarifies that the question is part of a competition, indicating a desire for assistance.
  • There is a discussion about the application of quantum numbers and the Aufbau principle, with one participant asserting that the same rules apply regardless of atomic number.
  • Another participant expresses skepticism about applying these rules to an element far outside the typical range of validity, questioning the appropriateness of such an application.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the applicability of the Aufbau principle to an element with such a high atomic number, with some asserting it can be applied while others challenge this perspective.

Contextual Notes

The discussion highlights uncertainties regarding the limits of the Aufbau principle and the assumptions underlying its application to elements with very high atomic numbers.

You have to show your attempts at answering the question, this is a forum policy. Also, all homework like questions should go to homework forum.
Hello,
Imagine a chemical element of the periodic classification with 2046 as atomic number.
The highest physicists will tell you that such an element is totally unstable.
It prevents not at all the rule of Klechkowski from applying to the atom of this element..

Would you know how to give me the filling of its last two electronic layers of valence ?

For Fe, it would be 4s2 3d6.

Thank you for your cooperation.

I apologise in advance about the spelling. I'm french student...

Thanks.
No, it's a problem which is a part of a competition: eurosciences junior.
You can help me ? :wink:
That isn't in the correct topic. You can change it please ?

Edit: OK !
 
It is a standard homework question, it resurfaces now and then at the forum.

It is all about quantum numbers and Aufbau principle. Do you know them?
 
Yes, I understand for an element with a "little" number atomic, but there...
 
Really for eurosciences junior ! It's harder... ?:)
 
Sure it is harder, wouldn't make sense if it were easy. It is meant to separate the men from the boys :wink:

As I said - it is about applying exactly the same rules. Tedious? Perhaps. Difficult? No.

Does it make sense to apply this rule completely outside its range of validity?
