Arrange the following elements by electronegativities

7.Arrange the following elements by electronegativities in ascending order based on their positions in the periodic table. Elements areB, O, Ga, Al, In. Explain. 8. Ionization energy and electron affinity of oxygen are 1313.9 kJ/mol and -142 kJ/mol respectively. What is the electron affinity of O + ion. Since the addition of electron to O + is exactly opposite reaction to its removal from O (first ionization) the reaction heat (affinity) should have the same value and the opposite sign so it is -1313.9 kJ/mol. 9. Ionization energy of one mole of Na is I=495kJ. What is the ionization energy of one sodium atom. Express in electron Volts. The energy in Joules is given by the ratio of molar energy and Avogadro’s number I/N A . To express it in electron Volts one should divide it by the electronic charge. This yields 5.14eV.

    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.
