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?
