Orbital diagrams, electron configuration, help please?
« on: September 17, 2013, 11:34:32 PM »
I was absent the day this got lectured so I am left stranded and I cant figure it out.
I did learn abbreviated electron configuration but my paper is asking for ground state electron configuration and I dont know what that means.

The abbreviated electron configuration for neon is [He] 2S21P6
What about the ground state?
Is that just having to actually write out the electron configuration for helium followed by the electron configuration for neon?
So it would look like
1S22s21P6 ?

And as for the orbital diagram, I dont understand it.
I go on google images and I see multiple interpretations of it.
Any guidance there?

And also, something we didn't cover but the teacher wants us to attempt it.
"Write the chemical symbol for the ion this atom would form"

So if I did Neon, I would guess that the ion formed would be Ne2-
Since it has two valence electrons.
Is this right?

Neon is 1s22s22s6 = [He]2s22s6
neon is a noble gas and normally it doesn't form an ion. It is only possible in neon tubes for lightning. With an electrical field some electrons can expelled and Ne+, Ne2+, etc. can be formed.

Mistake by me,sorry.

Ne = 1s22s22p6
