Nadine GhourraMs. ValerieH.Chem Chapter 6 assessment5 December 2019 41-1. Why do the elements chlorine, used in laundry bleach,and iodine, a nutrient added to the table salt, have similar chemical properties?-They have the same valence electron configuration s^2p^5.42-2. How is the energy level of an atom’s valence electrons related to its period in the periodic table?-The energy level of an atom's valence electrons equals its period number.43-3. How many valence electrons does each noble gas have?-Eight valence electrons but helium has two.44-4. What are the four blocks of the periodic table?-S,d,p,and f. 45-5. What are electron configuration has the greatest stability?-s^2p^6.46-6. Explain how an atom’s valence electron configuration determines its place in the periodic table.-Elements in a given column have the same number of valence electrons. The energy level of an atom's valence electrons determines its period.

    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.
