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?

calibax, couldn't that be just referring to the 2s 8s and 16s?

Don't think so factor, could the word or phrase be something to do with 'state'

I thought it was electronic configuration. Electron placement?

Is it mentioned in this article?

Thanks factor :)

Of course I meant to type ELECTRON (not electronic) CONFIGURATION. Another term could be orbital electron configuration
