For Al: 1s2 2s2 2p6 3s2 3p1.

For n=1, l=0 and m=0 a maximum of 2 electron.
For n=2, l=0 and m=0 a maximum of 2 electron.
For n=2, l=1 and m=0 a maximum of 2 electron.
For n=3, l=0 and m=0 a maximum of 2 electron.
For n=3, l=1 and m=0 a maximum of 1 electron.

If [ ] denote greatest integer, then ans must be 11.

$\text{Al} : [Ne] 3 s^2 3 p^1$ , you've instead stated $\text{Al} : [Ne] 3 s^2 2 p^1$ .
