Short hand?

Postby Mario Reyes 1C » Sun Apr 29, 2018 1:19 pm

When using short hand, when can you only use preceding inner gases? Why can't you use any other element before it?

Inert gases have a full outer energy shell, so using them is basically saying that the last energy shell is completely full, and then you add the rest of the configuration for whichever atom you are specifying. For example, if I was talking about carbon, I would say [He] 2s^2 2p^2 to say that n=1 is full, and then we have 2s^2 2p^2.
