Question

Theres this one question in my homework that says that there is an unusual but actual condensed configuration and they said to write it. Which element are they referring to? :S

Answer 1

when I said configuration I meant electron configuration

Answer 2

Hard to say. There are a number of elements that don't quite follow the rules. Any other hints to go by. Cu, Pd, the Au, Ag, Hg grouping are a little unusual.

Answer 3

Thank you :)
Could you also please answer the question below? I still don't understand it.

Answer 4

When I said below I meant on the actually forum; the previous question I posted.

Answer 5

I answered your last response below. Start a new thread if you have further comments about the same question. I think you just need to remember that these are ground states we are talking about, that the 2s is one orbital; the 2p are three different orbitals, and that Hund's rule comes into play when filling the p orbitals but not when filling the s orbital (since it can only be 1 or 2 electrons). As for promotion, it occurs but those configurations are not for the ground state.

Answer 6

I finally understand it. Thank you so much!
