Electron Configurations of Ions

[Bronson Mathos 1H]

Hello, I was just wondering if electron configurations of ions are done by simply doing the same electron configuration except adding or removing an electron from the last orbital?

[MMorcus2E]

Yes, that sounds about right!

[Hazelle Gunawan 3G]

Yep, that's correct! Be careful when you're dealing with transition metals, though, because (for example) generally the 4s electrons are added/removed before the 3d electrons because they have lower energy. This tripped me up on the last midterm so I just wanted to mention it!

[Evelyn Silva 3J]

Yes, first you write the electron configuration for a neutral atom and then you add or remove the electrons from it
