What is the general electronic configuration of transition elements

Options

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)`

Answer

D

Explanation

Generally, d-block elements are called transton elements as they contain nner partially filled d-subshell. Thus their general e electronic configuration is `(n-1)d^(1-10), ns^(1-2)`
