N=3 m=0 I=1 s=-1/2 then find element name and atomic no

1.	N=3 m=0 I=1 s=-1/2 then find element name and atomic no
Answer» n = 3 means third shell I = 0 means s subshell of third shell. m = 0 means EITHER 3S has I or 2 electrons ∴ Electronic configuration is Is 2,2s 2,2P 6,3S 1OR 3S 2 ∴ Atomic NUMBER is 11 or 12

Answer»

n = 3 means third shell

I = 0 means s subshell of third shell.

m = 0 means EITHER 3S has I or 2 electrons

∴ Electronic configuration is

Is 2,2s 2,2P 6,3S 1OR 3S 2

∴ Atomic NUMBER is 11 or 12
