AI Thread Summary
The discussion revolves around the hypothetical chemical element with an atomic number of 2046, which is deemed unstable by physicists. Participants debate the application of the Klechkowski rule to determine the element's last two electronic layers of valence, specifically in the context of a competition problem for Eurosciences Junior. While some find the task tedious, others assert that it is not difficult if one applies the same quantum rules as for lower atomic numbers. The conversation highlights the challenge of extending established principles to elements far beyond the current periodic table. Ultimately, the discussion emphasizes the importance of understanding quantum numbers and the Aufbau principle in this context.

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?
