Electron Configuration Ruthenium (Electron configuration exceptions)

Показать описание
Electron configuration Ruthenium
Ruthenium has an atomic number of 44 and has 44 electrons.
It is an exception to the normal rules of electron configuration because instead of having filled the 5s orbital with 2 electrons and the 4d orbital with 6, Ruthenium fills the 5s orbital with 2 electrons and the 4d orbital with 7 electrons.

It would ve more helpful to say why they are more stable or explain the exception. I could just google what you said in the video.

lol u didnt even explain why it is deviant, like why is it more stable with that configuration

Why wasn't it explained? That's why we are all here.

Why is it 5s1 4d7 and not 5s2 4d6? What is the reason of showing this exception ?

Lol u didn't explain the reason why most people coming here r for the explanation just like me.

I believe it's because half filled s orbitals are more stable so there is 5s1

I got this wrong on aktiv chemistry for my college class thanks to you. The correct answer is Kr 5s2 4d6
Thanks for nothing!

How many Valance electrons does ruthenium have? 😢

Your comment MooMath on the Ru exception should read, I believe, "...Ruthenium fills the 5s orbital with 1 electron and the 4d orbital with 7 electrons."
