plz explain your answer

14. Chapter: 4 Lesson: 2 Question: Use the Interactive Periodic Table to answer the following questions about ionization energy. I. What is the first ionization energy (IE1 ) of sulfur (atomic number 16 )? II. Write the expressions for the successive ionization energies of S(IE1 to IE7) ? III. Plot the successive ionization energies of S(IE1 to IE7). IV. What trend is seen in this plot? How do you explain the change in slope associated with the IE7 ? Hint: What are the definitions of IE1,IE2, etc? Note: you can use the interactive periodic table to generate the plot requested in III. See this sample problem if you need help
