Problem 1E.5

Postby Jessica Tejero 3L » Sun Oct 20, 2019 7:19 pm

Can someone explain part b to me

1E.5 Which of the following statements are true for many-electron atoms? If false, explain why. (a) The effective nuclear charge
Zeffe 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 5 2 are better at shielding than
electrons having l 5 1. (d) Zeff e for an electron in a p-orbital is
lower than for an electron in an s -orbital in the same shell.

Electrons in an s-orbital are more effective at shielding other electrons because the penetration levels go ns > np > nd > nf. The higher the penetration the more effective an electron is at shielding others. The s-orbital is closest to the nucleus so it is the most effective at shielding other electrons that are further away.

What does Zeffe mean in this context?
