What is the estimated effective nuclear charge, Z eff, experienced by an electron in a 3 p orbital of a chlorine atom? Effective nuclear charge per electron is reduced and the electron cloud is held less tightly by the nucleus. The reason is that there is an extra shell of electrons for every period down a group. The effective nuclear charge is always less than the total number of protons present in a nucleus due to the shielding effect. The outer shell is #3. c) How do the effective nuclear charges of sodium and chlorine affect their relative atomic radii?
