2.37 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 having l 2 are better at shielding than electrons having l 1. (d) Zeff for an electron in a p-orbital is lower than for an electron in an s-orbital in the same shell.
For part b, in the solutions manual, it says that electrons in s orbital can penetrate to the nucleus of an atom. What does it mean to penetrate to the nucleus?
