11) Below is a list of successive ionization energies (in kJ/mol) for a period 3 element. Identify the element and explain how you came to that conclusion. IE2 = 2250IE3 = 3360IE4= 4560 IE5= 7010IE6= 8500IE7 = 27,100 12) Why do successive ionization energies increase? 13) Why is the first ionization energy of sulfur smaller than the first ionization energy of phosphorus? 14) Give the ground state electron configuration for Cd+2. 15) Define electron affinity. 16) Why do Li, Na, and K have similar chemical properties?
