Effective Nuclear Charge In a many-electron atom, each electron is simultaneously: attracted to the protons in the nucleus repelled by other electrons (like-charge repulsion) What is the average environment, created by the nucleus and all the other electrons in the atom, which is "felt" by a particular electron in the atom? The net positive charge attracting the electron is called the effective nuclear charge Any electron density between the nucleus and the electron of interest will reduce the nuclear charge acting on that electron The effective nuclear charge ( Z eff ) equals the number of protons in the nucleus ( Z ), minus the average number of electrons ( S ) that are between the electron in question and the nucleus The positive charge "felt" by the outer electrons is always less than the full nuclear charge (inner electrons "screen" the nuclear charge). Energies of orbitals The extent to which an electron will be screened by the other electrons depends on the

    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.
