Electron Configuration form
Will we be told when to write a configuration the longer way or shorter way? for example [NE] vs. 2s2 2p5

Re: Electron Configuration form
I’m assuming we can use the shorthand unless otherwise stated, since that’s how they have it in the solutions manual.

Unless otherwise stated, you can use shorthand. For example, for Ca you can write [Ar] 4s2 instead of writing 1s22s22p63s23p64s2

Re: Electron Configuration form
However, there are 2 exceptions that were mentioned in lecture where you can write the shorthand for the electron configurations, but they do not follow the typical rule when it comes to writing their electron configurations.
CHROMIUM (Cr): [Ar] 3d5 4s1, not [Ar] 3d4 4s2
COPPER (Cu): [Ar] 3d10 4s1, not [Ar] 3d9 4s2
CHROMIUM (Cr): [Ar] 3d5 4s1, not [Ar] 3d4 4s2
COPPER (Cu): [Ar] 3d10 4s1, not [Ar] 3d9 4s2

Re: Electron Configuration form
It would not be incorrect to use shorthand, but it is better to show the electron configurations because they provide more detail. For example, the shorthand for K+ is [Ar] but it is better to write it out as [Ne] 3s^2 3p^6.
