Give the electron configuration?

of

Na+1
Al
Cl
O-2

Answer:
Note: I put parenthesis around everything simply because I don't know how to make superscripts on this site, but normal electron configs. wouldn't have them.

--Na+1 is (you basically use the configuration for Ne because Na+1 has one less electron than Na):
(1s^2)(2s^2)(2p^6)

--Al is:
(1s^2)(2s^2)(2p^6)(3s^2)(3p^1)

--Cl is:
(1s^2)(2s^2)(2p^6)(3s^2)(3p^5)

--O-2 is (you basically use the configuration for Ne because O-2 has to more electrons than O):
The same configuration as Na+1
