Electron Configurat… - QuestionCove

Electron Configuration question: How do you write the electron configuration if an Element has a charge? Example: V^5+ I heard that p and s blocks get taken off respectively before the d block. But how would it look like?

you remove electrons that are higher in energy (e.g. 4s electrons before 3d electrons) so for vanadium, you have $$\sf [Ar]3d^34s^2$$ you remove the 2 4s elctrons and the 3 3d electrons, leaving with you just the electronic configuration of Ar.

Thanks. So you remove s electrons and d next? What about the p electrons?

the 3p electrons would be next, but it's not really common for vanadium to lose some many electrons because it would take too much energy.

Okay. I think I got it. Thanks!

No problem. If you have another example you can post what you think the answer is and i can check it.

Let's say it's Ni2+ would the electron config be [Ar]3d^8 ?
