- 1.67 Which of the following statements are true for many-electron atoms? If false, explain why. (a) The effective nuclear charge Zeff is independent of the number of electrons present in an atom. (b) Electrons in an s-orbital are more effective than those in other orbitals at shielding other electrons from the nuclear charge because an electron in an s-orbital can penetrate to the nucleus of the atom. (c) Electrons havingl = 2 are better at shielding than electrons havingl = 1.
