Electron Configuration of Cations Valence e-s in highest n quantum number are lost firs When valence e-s have the same n, the e-s in the highest l quantum number are lost first. Section 4.2 Any engineer knows the e-s are NOT removed in the reverse order they came in. Remove valence p, then s, then d. 8

    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.
