The correct set of four quantum numbers for the outermost electron of sodium (Z=11) is 3,0,0, 1/2

The electronic configuration of Na is 1s

2/ 2s

2/2p

6/ 3s × 1

Thus, the last electron is in 3s sub-shell.

For 3s sub-shell, n=3,

l=0, m=0 and s=± 1/2

Answer:

n=3, l=0(s),m=0, s=+-1/2

Explanation:

last electron is in 3rd shell. So n=3.

Only one electron present, hence l=0(s subshell).

Since l=0, therefore m=0.

Spin quantum no.-(s) can take any value, +1/2 or-1/2.

Hope I hv cleared your doubt.
