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.

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 ?

yes
