[1991, 2002]

(a) (n−2)f1−14(n−1)s2p6d0−1ns2

(b) (n−2)f10−14(n−1)d0−1ns2

(c) (n−2)f0−14(n−1)d10ns2

(d) (n−2)d0−1(n−1)f1−14ns2

Show Answer

Solution:

  1. (a) The Lanthanides are transition metals from atomic numbers 58(Ce) to 71(Lu).

Hence the electronic configuration becomes :

(n−2)f1−14(n−1)s2p6d0−1ns2
