You gots sulfur, #Z=16...#

Explanation:

And we use the #"aufbau principle"# to specify the electronic configuration of the 16 electrons....

#S:1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)#

Now the valence electrons clearly have #n=3#...they are #p# electrons, so #l=1#, i.e. there is ONE orbital node...#m_l=-1,0,+1#...depending on the orbital orientation....with the #x,y,z# axis....and #m_s=+-1/2#
