### Electron Configuration

When we are asked to write down the electron configuration for Nitrogen for example, do we have to write 1s^2 2s^2 2px^1 2py^1 2pz^1 or can we simply just write 1s^1 2s^2 2p^3 ? Thank you in advance!

Dr. Lavelle said it's okay to write it as 1s^1 2s^2 2p^3!

How do we know when we are able to use the "shortcut"? Or will both be accepted?
By shortcut, I mean using the noble gas? [He] 2s^2, 2p^3

### Re: Electron Configuration

when writing the electron configuration i have noticed one professor write the largest number
then count down to 1s portion (2p^6, 2s^2, 1s^2)... is that only when we use the short method that takes the noble gas or...?
