Q. The general electronic configuration of the transition elements is
A) $(n - 1)d^{10},\ (n + 1)s^{2}\$
B) $(n - 1)d^{1 - 10},(n + 1)s^{1 - 2}$
C) $(n - 1)d^{1 - 10},np^{6},\ ns^{2}$
D) $(n - 1)d^{1 - 10},\ ns^{1 - 2}$
Explanation
(d)
Generally, d-block elements are called transition elements as they contain inner partially filled d-subshell. Thus, their general electronic configuration is $(n - 1)d^{1 - 10},\ n^{1 - 2}$.
