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. (d) Zeff for an electron in a p-orbital is lower than for an electron in an s-orbital in the same shell

Transcribed Image Text: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. (d) Zeff for an electron in a p-orbital is
lower than for an electron in an s-orbital in the same shell
