Ru3+ Electron Configuration

What is the electronic configuration of Ru 3+? 3

What is the electronic configuration of Ru 3+?

(A) [Kr] 5s 2 4d 9

(B) [Kr] 5s 2 4d 4

(C) [Kr] 5s 0 4d 5

(D) [Kr] 5s 2 4d 6

(E) [Kr] 5s 1 4d 5

The answer is (c). The total number of valence electrons in the neutral Ru atom is 8. However, Ru3 + has only 5 valence electrons. Of the 5 available cycles, only (c) has a total of 5 valence electrons.

(D) [Kr] 5s 2 4d 6

(E) [Kr] 5s 1 4d 5

Why is the electron configuration [Kr] 5s 2 4d 3 instead of ru3 + [Kr] 5s 0 4d 5?

Paired electrons in 3S are more stable and have less energy than 4 non-paired electrons

Because the oral likes to fill 5 or 10 electrons because it is more stable

I want to ask this question too, huh
