[Kr] 4d¹⁰

Whenever we remove electrons do we always remove it from the s orbital in that period. So for cadium ion we remove 5s² correct? But let's say it's Mn ²⁺ would we remove the electrons from 4s?

In general we remove electrons in exactly opposite order we put them on the atom - do you know the Aufbau principle?

There are several exclusions though.

Okay I see, yes I know the Aufbau principle.
