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?

Best ResponseYou've already chosen the best response.2Yeah. Ok your electron "orbital" filling rules are 1s,2s,2p,3s,3p...

Best ResponseYou've already chosen the best response.2s orbitals can take 2 electrons max. P orbitals can take 6.

Best ResponseYou've already chosen the best response.2We 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.

Best ResponseYou've already chosen the best response.2Now 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.

Best ResponseYou've already chosen the best response.2well, Ne has 11 electrons. We get:\[1s^2,2s^2,2p^63s^1\]Not enough electrons to be Ne

Best ResponseYou've already chosen the best response.2It could be an exited state of \[Ne^{2}\] though....

Best ResponseYou've already chosen the best response.2But yeah, I think that narrows it down for you :)
