Chemistry key word - electron configuration

I know how to do this certain thing in chemistry, and have even done a past exam question on it, but can't remember what the terminology is that describes it and I can't find that past exam in my folder.

It's when you're asked to write out the electron configuration of an atom or ion, in a specific way.

For example; Lithium is 1s2, 2s2 and Boron is 1s2, 2s2, 2p1 but a Boron 1+ ion would be 1s2, 2s2.

Any ideas?

What's in a mirror when no one's looking at it?

Just how toxic is mercury?

Whether one gives the correct answer or not it's the polite thing to say thanks to everyone. If not everyone, I'm sure most took the time and effort to search for the answer for you. I'm just saying...
