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
    $(n-1) d^{1-10}, n p^{6}, n s^{2}$
  • Correct answer
    D
    $(n-1) d^{1-10}, n s^{1-2}$

Solution

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

Hence, the correct answer is option: 'D'.
