ionisation energy

explain why the first ionisation energy of sulphur is lower than would be predicted from the general trend.

im assuming the answer is to do with the electron configuration being unstable in the 3p4 shell and therefore the electrons repel more reducing the attraction towards the nucleus making the ie lower than required?
im not sure how to word this correctly for the exam question?
am i right?
please help it is a homework question.
thank you in advance
