What is the atom for the electron configuration [Ne]3s1 3p1? is it Mg or Ne-? and just to make sure,, this is an excited state right?

@eseidl please help on my question

after this ?
anonymous

Yeah. Ok your electron "orbital" filling rules are 1s,2s,2p,3s,3p...
anonymous
  • anonymous
s orbitals can take 2 electrons max. P orbitals can take 6.
anonymous
  • anonymous
but why isnt it Ne-?
anonymous
  • anonymous
We fill 3s BEFORE 3p. Since 3s only has one electron in the s orbital, but also has one in the p orbital, it is an excited state.

  • anonymous
oh it it because itll give it an extra electron?
anonymous
  • anonymous
is it*

Now why is it Mg...well, Mg is atomic number 12. So, the neutral atom has 12 electrons. We get: \[1s^2,2s^2,2p^63s^2\]for the neutral atom. But if we exited the atom, bumping 1 electron into the 3p orbital, we have a (slightly) excited Mg atom.

oh ok thanks!!!

Why isn't it Ne-...
anonymous
  • anonymous
well, Ne- has 11 electrons. We get:\[1s^2,2s^2,2p^63s^1\]Not enough electrons to be Ne-
anonymous
  • anonymous
oh ok! thanks again!
anonymous
  • anonymous
It could be an exited state of \[Ne^{-2}\] though....

But yeah, I think that narrows it down for you :)
