magnesium (Mg)? 1s²2s²2px²2py²2pz²3s² = 1s^2 2s^2 2p^6 3s^2
there are three kinds of p orbitals, px, py,pz,difference in geometry but all are capable of holding 2 electrons.
***
for those ppl thinking about fluorine, first of all, it has 2 x 6 = 12 electrons, not 9 (^^). Fluorine has five 2p electrons, this element has six; also, this element has two valance electrons (the outmost 3s orbital), not seven. So definitely NOT fluorine, I can guarantee u that.

If you add up the superscripts you get 9 electrons. The 9th element in the periodic table is fluorine.

Actually when you add the superscripts you get 12 which would be Mg. YAY!

i think its flourine because there are 7 valance electrons and it has 3 energy levels
