What is the ground-state electron configuration of a neutral atom of sodium?

Well, you gots sodium, Z=11...

Explanation:

And so in the neutral atom, we gots ELEVEN electrons to distribute...

1s^(2)2s^(2)2p^(6)3s^(1)

And, as is typical, this electronic configuration reflects Periodic Structure....sodium is an "s-block element". We gots Z=11, that starts on the THIRD PERIOD, with a SINGLE 3s electron....

Sodium metal is thus a good reducing agent that readily forms Na^+...what is the electronic structure of this ion.....and to which NEUTRAL atom is it equivalent?
