Question

The general electronic configuration of the transition elements is

• A. $\left(n-1\right)d^{10}$ , $\left(n+1\right)s^{2}$
• B. $\left(n-1\right)d^{1-10}$ , $\left(n+1\right)s^{1-2}$
• C. $\left(n-1\right)d^{1-10}$ , $np^{6}$ , $ns^{2}$
• D. $\left(n-1\right)d^{1-10}$ , $ns^{1-2}$

Answer 1

Answer: (D)

$\left(n-1\right)d^{1-10}$ , $ns^{1-2}$

Answer 2

Generally, $d$ -block elements are called transition elements as they contain inner partially filled $d$ -subshell. Thus, their general electronic configuration is $(n-1) d^{1-10}, n s^{1-2}$.
