Using shorthand [Ar] [ENDORSED]

[Maria Trujillo 1L]

In regards to using short hand, for example, Ca: [Ar] 4s^2 and Br: 3d^10 4s^2 4p^5, are we allowed to use Neon or Helium, or is it only after Argon that we are allowed to use this shorthand? Like can we do this regarding shorthand, Na: [Ne] 3s^1

Thank you!

Since it isn't very informative when you just but [Ar] for shorthand it would be safer to just use the noble gas before it and write full orbitals.

[Jasmine Emtage-1J]

I believe we can use any of the noble gases in our shorthand. Hope that helps!

[Ismail 1F]

Yes, you can use that for shorthand. Any noble gas will work, as long as it is the closest one.

[Samantha Draghi 1L]

I think you can use any of the noble gases that come previous to the element you are describing.

[Alexis Bravo 1D]

I think the closest noble gas would probably be best for the shorthand.
