### Writing Electron Configurations

How do we know when to include x, y, and z when writing electron configurations? For example, nitrogen is 1s^2, 2s^2, 2px^1, 2py^1, 2pz^1

I think in general you don't include the x, y, z. I know for sure that you don't use it for d orbitals.

I know that in high school, we never wrote the x, y, z, in the electron configurations, but I think I remember that during lecture on Friday, Dr. Lavelle mentioned that he wouldn't mind if we wrote out the x, y, z to show that we understand the meaning of it.

I think we just write that when we need to show that, like in your nitrogen example, the three electrons in the 2p state are occupying different orbitals.

I'm not sure whether or not it matters if you include it, because it means the same thing either way, but the x, y, and z only exists for p-orbitals.

As Lavelle said, it is to demonstrate understanding but the regular way to do it isn't wrong in itself. I would stick with that method.

yup just to add on, you could either write nitrogen is 1s^2, 2s^2, 2px^1, 2py^1, 2pz^1, or nitrogen is 1s^2, 2s^2, 2p^3 and both would be correct

### Re: Writing Electron Configurations

you don't need to write x, y, or z next to your electron configurations. I think Dr. Lavelle just put that in lecture as extra information but for now dont' worry about it.
