Could someone please explain to me in simple terms as to why sulfur has has valence of 4 in the radical SO3 and a valence of 6 in the radical SO4?

Do you talk about radicals or Ions.

SO32- has 3 * (-2)(O) + x(S) = -2(Charge)  For x (sulfur) you will get +4. The same for SO42- you will get +6 for sulfur.

If you talk about radical specify the molecule.
