Which Element Has These Successive Ionization Energies in Period 3?

[Kelly09]

i am stuck on this question and people are giving me different answers. Ok which period 3 element has the following succesive ionization energies: 1800,3000,3600,5800,13200

 

[Char. Limit]

Just look up the ionization energies of all of the period three elements... there's only 8...

I would guess Silicon, because of the large gap between fourth and fifth energies...
