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
It is [Xe] 6s2 5d1 4f6 because lanthanum is a d-sublevel element because it takes less energy to put the one electron in the 5d sublevel due to the orbital shapes than to put it in the 4f sublevel
Yes, your electron configuration for Europium is almost correct. However, the f-block electron configuration should be 4f7, not 4f6.
To understand how to determine the electron configuration for Europium, let's go step by step through the periodic table:
1s2 2s2 2p6 represents the electron configuration of the first three energy levels, the 1s, 2s, and 2p sublevels.
3s2 3p6 represents the electron configuration of the third energy level, the 3s and 3p sublevels.
4s2 3d10 represents the electron configuration of the fourth energy level, the 4s and 3d sublevels.
5s2 4d10 represents the electron configuration of the fifth energy level, the 5s and 4d sublevels.
Now we move on to the f-block, where Europium belongs. Europium has an atomic number of 63, which implies that it has 63 electrons. To complete the electron configuration, we need to fill the 6s and 4f sublevels.
The f-block consists of 14 elements called the lanthanides, and their electron configurations fill up the 4f sublevel. The general electron configuration for the lanthanides is [Xe] 4f^n 6s^2.
Since Europium is the 63rd element, it comes after the element gadolinium (Gd), which has an electron configuration of [Xe] 4f^7 5d^1 6s^2. To determine Europium's electron configuration, we remove the 5d^1 part and keep the 4f^7 6s^2 part.
Therefore, the correct electron configuration for Europium is:
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f7.
This representation shows the distribution of 63 electrons in Europium's energy levels and sublevels.
