Noble Gas Shortcut

Postby Jason Wu 1E » Fri Oct 18, 2019 4:23 pm

What are the specifics to using the Noble Gas shortcut? Additionally, for example, to write the electron configuration for Argon, are you allowed to just write [Ar]? or do you have to write [Ne] 3s^2 3p^6?

You use the noble gas that's the closest one before the element you are describing, and I'm pretty sure you can just do [Ar] for argon.

You use the noble gas that is the one closest one before the element, so typically it'll be a row above the element you're working on. You should be able to just write [Ar] for argon.

I don't think you can just write [Ar] for Argon. You won't be writing any actual configuration then. I'm pretty sure for noble gases, you have to use the previous one and write out all the valence electrons.
