How do we write the shorthand configuration of elements and/or ions in their ground states?

Do you mean the [Ar]4s13d5 kind of shorthand? :-)

You can write the shorthand configuration of elements by going back to the nearest noble gas before it (in atomic number), then account for the electrons after that noble gas. Say, for example, you have Arsenic (As). The shorthand would be As: [Ar]4s^2 3d^10 4p^3.
