As you go from left to right, you go from low ionization energy to high ionization energy.

WebIonisation energy is the energy required to remove one electron from a neutral atom of an element. S and Se belong to VIA group elements. Down the group ionisation energy decreases so S is having more IE value than Se. S and Cl are the elements of the same period the IE value increases from left to right. So, Cl is having more IE value than S.
