Unformatted text preview: nucleus pulls them closer and the ion size shrinks. K Ar Cl S 2 These ions are isoelectronic with each other. (They all have the same number of electrons.) S 2 has the smallest nucleus and K the largest nucleus. So K will be the smallest and S 2 the largest. A larger nucleus will pull the electrons closer making the atom smaller. 8. Which of these orbitals experiences the largest screening effects? 1 s , 2 s , 2 p , 4 f 4 f 9. Which electron has a larger Z eff a. A 1 s electron in H or a 1 s electron in Li? Li because the nucleus in Li is larger. b. A 2 p electron or a 3 p electron of S? 2 p . The 3 p electron is further from the nucleus on average and will experience more screening effects. 10. Which of these elements has the most metallic character? Li, Na, Rb, Mn, Cu Rb...

    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.
