The electron configuration for Europium?
I think it's
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f7
Is that right? I'm not sure if I did it right with the f block.
Scroll down about 1/2 page.
Oh.. well we haven't learned the shorthand configuration yet so really don't know if my answer is correct or not
The short hand configuration is quite straight forward For Eu it is
[Xe] 4f7 6s2
the [Xe] is the electron configuration of xenon, the nobel gas before Eu, which has full electronic configuration of
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6
or if you like [Kr]5s2 4d10 5p6
Hope this helps
