Quiz 5 Chem 1303.001 General Chemistry Fall 2018 KEY 1.10 pts eachThe first four ionization energies (in kJ/mol) of an element are approximately 579, 1980, 2963, and 6180, respectively.To which periodic group does this element belong?Explain. Group 3A (or 3B). See answer to HW problem 8.130. The large increase between the 3rdand 4thIE suggest an electronis being removed from the core for the 4thIE.Write the FULL (do not use the shorthand square bracket notation) ground state electron configuration of Te2–(Z= 52)1s22s22p63s23p64s23d104p65s24d105p6Write the FULL (do not use the shorthand square bracket notation) ground state electron configuration of Ni4+.1s22s22p63s23p63d6The Hion and the He atom have two 1selectrons each. Which of the two species islarger?Explain.The Hion is larger. See answer to HW problem 8.48. The two electrons only feel the attractive force of one proton inthe hydrogen nucleus, while the two electrons in helium feel the attractive force of two protons in the helium nucleus.Also, anions are generally larger than neutrals or cations.Arrange the following elements in order of INCREASING (left to right)firstionization energy:

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
